Constructing Congruent Line Segments and Angles, Perpendicular Bisectors of Line Segments, and Bisecting Angles.
Students identify perpendicular bisectors and angles. In this geometry lesson, students, construct and identify angles. They construct, measure, and identify line segments.
Constructing Angles Part I: Bisecting the Angle
In this math activity, high schoolers practice bisecting angles. This activity has many problems for the students to solve and includes and answer sheet.
Ruler and Compass Constructions
Fourth and fifth graders examine how to construct perpendicular lines and to bisect angles using rulers and compasses in this unit of lessons. They design a number of polygons using these methods.
In this geometry worksheet, students use protractors and rulers to draw 6 lines, rays, and triangles using the given measurements. They follow directions as to which lines bisects angles and other lines.
Five Multiple Choice Bisecting Angles Problems
In this bisector worksheet, students solve five multiple choice problems regarding bisecting angles. Hints and solutions are provided.
New! Finding the Area of an Equilateral Triangle
The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle to solve. Here the objective is to get geometry learners develop an understanding of two new solutions. One using congruent triangles, and the other using trigonometric ratios.
SAT Prep: Test 5 Section 3 Part 4
Explaining that the only thing he gets in return for these videos "is the satisfaction of you guys getting a perfect score on the SAT," Sal charges on through the practice SAT problems. Students who have a difficulty with parabolas and graphing functions would find this video very helpful as they prepare to take the exam.
Get to the Point! Coordinate Geometry!
Tenth graders explore area of polygons. They find the areas of geoboard polygons using the coordinate method. Additionally, learners investigate problem solving using a coordinate approach.
Discovering Math: Exploring Geometry
Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade with classmates, who calculate surface area and volume of some of the structures. Refers to a Discovery Education video/DVD to support and enrich the project; a link takes you to a website to order it. Charts mentioned are not attached.
Geometric Investigations of the Voyage 200 with Cabri
Tenth graders explore quadrilaterals and triangles. In this geometry lesson, 10th graders examine kites, trapezoids, parallelogram, rectangle, rhombi, squares, and triangles and explore the properties of the various figures. The dynamic nature of the geometry utility facilitates measurement and conjecture regarding the properties.
Students use a problem in a real-world context to motivate the need to construct circumcenters and then incenters of triangles and to make sense of these constructions in terms of bisecting sides and angles.
Polygon Sum Conjecture
In this geometry worksheet, 10th graders identify the missing angles using the polygons sum conjecture. They measure exterior and interior angles using their angle theorems. There are 63 problems.
Points of Concurrency related to Archaeology-Grade Ten
Eleventh graders discover the properties of the points of concurrency of a triangle. In this geometry lesson plan, 11th graders use paper folding, interactive geometry software, and construction to investigate the points of concurrency. Use of a real world problem provides context for the lesson plan.
Building Blocks of Geometry
In this geometry worksheet, students answer questions about midpoints, distance, lines and segments. They are given different shapes and asked to calculate the angles, and sides of polygons.
Say Hello to the Quadrilateral Family!
Fourth graders work in groups to create intersecting lines on geoboards. They discuss knowledge of polygons. Students complete a "Properties of the Quadrilateral Famly" chart as the class combines information from their geoboards and discusses the shapes that have been created. Students complete Venn Diagrams to compare properties of quadrilaterals.
Students construct lines and segments. In this geometry lesson, students practice drawing geometric shapes. They discuss similarity and differences as well as ratios.
Review of Geometry I
In this review worksheet, students identify the characteristics of intersecting and parallel lines They explore vertical, supplementary, alternate interior, alternate exterior and corresponding angles. This two-page worksheet contains approximately 50 multiple-choice problems.
Points of Concurrency Related to Archaeology
Tenth graders participate in a lesson about the points of concurrency. Students should understand properties of triangles to solve problems and use proportions to express relationships among corresponding parts of similar figures.
The Orthocenter of a Triangle
Tenth graders define the orthocenter of a triangle. In this triangles lesson, 10th graders draw and label a triangle shown and construct the altitudes to locate the orthocenter. Students hide the altitudes and drag the triangle to explain where the orthocenter is located for different types of triangles. Students also construct a nine-point circle for a new figure formed and compare it to the original figure.
Constructions and Loci
In this constructions and loci activity, students create a scale drawing of a running track. They identify the starting positions for a given race. Students bisect angles. They construct an angle trisector. This three page activity contains three multi-step problems.
