I Can Name that Angle in One Measure! - Grade Eight
Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a transversal. This sharp lesson plan gets the class to investigate a real-world situation requiring finding an angle that cannot be measured directly.
Angles Formed Between Transversals and Parallel Lines
While exploring the concept of transversals, Sal discusses corresponding angles, congruent angles, and opposite/vertical angles. He provides a thorough summation of these mathematical concepts. It is the first installment in a series covering parallel lines.
Angles of Parallel Lines 2
Providing an exploration of parallel lines, this resource requires students to not only practice calculations, but also to analyze angles. By asking viewers to decide whether two lines are parallel based upon the information given, this second part of the parallel lines series becomes a critical-thinking activity.
Angles (part 2)
In this second video in the series on angles, students explore the concept of supplementary and complementary angles. In addition, intersecting lines and opposite angles are explained.
Angles (Part 3)
As a preparation for something called the angle game, a geometry video covers the concept of parallel lines, transversals, slope, opposite angles and corresponding angles. It is the third part of a series detailing the rules and laws regarding angles.
Looking at Things from Different Angles
Junior geometers define and provide examples of different angles. Acting as emerging engineers, they take hands-on and computer-centered approaches to explore an alternate interior, alternate exterior, adjacent, corresponding, right, obtuse, and acute angles.
Tenth graders identify special pair angles. In this geometry activity, 10th graders identify linear pair, adjacent, vertical and supplementary angles. they differentiate between the similarity and difference of these measurements and how to relate to each other.
Transverse and Longitudinal Waves
It is not a unique or exciting lesson, but rather the typical demonstrations of transverse and longitudinal waves. Use a rope for modeling transverse waves, and a plastic coil or spring toy for longitudinal waves. Where this resource may most come in handy, is if you are teaching waves for the first time or need a refresher. The background information and lesson procedure are explained quite well.
Angles, Lines, and Transversals
Geometers identify and determine angle pair relationships when two parallel lines are intersected by a transversal. They review the concepts of angles by watching streaming video clips online, read definitions of lines and angles from index cards, and match vocabulary with their definitions. They use the SMART board to demonstrate the content.
Meet Me at the Corner
Geometers use their knowledge of vertical, alternate interior, and corresponding angles in a real-world activity. Engineers plan to install guard rails at dangerous intersections of a city and need to know the angle at which to construct the rails. Students use a map of the city and work in groups to find various angle measures formed by intersecting streets. They even write a proof to convince the engineers that their measurements are correct. The resource includes follow-up questions and two good extension activities.
Explore, investigate, and finally prove the angles in a triangle have a sum of 180 degrees. Young geometers use the Interior Angles Theorem, and properties and definitions of congruency.
Parallel Lines Cut by a Transversal
Geometers explore parallel lines. In this lesson, they examine the measures of the angles form when parallel lines are cut by a transversal. The dynamic nature of the Cabri Jr. allows students to discover the relationships between the various angles in the figure.
Parallel Lines the Transversals that Cross them!
Middle schoolers explore parallel lines. In this middle school geometry lesson, students explore the relationships between angles formed by parallel lines cut by a transversal. The dynamic nature of the TI-Nspire or TI-Nspire CAS technology allows middle schoolers to form and verify conjectures regarding angle measurement.
Special Angles on Parallel Lines
Tenth graders investigate parallel lines and their special angles cut by a transversal. In this geometry lesson plan, 10th graders identify and find corresponding, alternate interior, and alternate exterior angles formed when parallel lines are cut by a transversal. They define the theorem that represents these angles.
Lesson Plan: I Can Name That Angle in One Measure!
In this angle lesson, eighth and ninth graders explore angles made using parallel lines and a transversal. They identify the types of angles and the characteristics of each one. Puils create drawings that illustrate angle relationships in real world situations, and determine the measures of angles.
Fun With Angles
Students visualize the different angles (corresponding, alternate interior, and same-side interior) when coplanar lines are cut by a transversal. They utilize worksheets imbedded in this plan to do their explorations with.
Are they Special Angles?
Students study the concept of special angles. In this special angles lesson, students use reasoning to draw conclusions about special angle relationships concerning parallel lines cut by a transversal. Students also list all pairs of corresponding angle shown in the diagram and write a conjecture describing what they observe about corresponding angles.
Tenth graders explore the angle relationships that exist when two lines intersect. In this geometry instructional activity, 10th graders estimate the measure of given angles and use their graphing calculator tools. Students use this knowledge to find the missing angle measures in given diagrams; using their device's tools to confirm their results for each problem.
Geometry - Angles Overview
Learners address 14 questions that include naming all pairs of opposite and supplementary angles for sets of intersecting lines and then, finding the measure of the unknown angle. They determine the measure of the angle that is complementary to the one given. They identify pairs of angles as alternate or corresponding and then, find the measure of each unknown angle. Finally they are challenged with figuring the measurements of unknown angles in polygons.
Are They Special Angles?
Middle schoolers identify the correspondence between pairs of angles. They fill in the blank for seven questions. Learners investigate congruency using their graphing calculator and by following detailed directions. They identify alternate exterior angles on their graphing calculator. There are seven calculator problems and four questions about a pair of parallel lines cut by a transversal.
