Tenth graders explore parallel lines cut by a transversal. In this geometry lesson plan, 10th graders determine if two lines are parallel, based on the measure of the interior angle pair on the same side of the transversal.
Tenth graders explore parallel lines cut by a transversal. In this geometry lesson, 10th graders explore the relationships that exist among the eight angles formed when parallel lines are cut by a transversal. The dynamic nature of Cabri Jr. allows for conjecture and verification regarding the angle relationships.
Tenth graders investigate parallel lines. In this geometry lesson, 10th graders explore the measures of the angle formed when parallel lines are cut by a transversal. This lesson focuses on the sum of the measures of the two interior angles on the same side of the transversal. The dynamic nature of Cabri Jr. allows students to form and verify conjectures.
In this geometry worksheet, students construct angles and identify medians and altitudes. They use a compass and protractor to perform heir construction. There are 28 questions.
Tenth graders explore lines, circles and planes using CabriJr. In this technology lesson, 10th graders further their knowledge of geometric terms using CabriJr. This assignment requires the software CabriJr loaded onto the TI.
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.
Take geometry into the real world! You'll find just about everything you need for a fun group project reinforcing terms such as: quadrilateral, parallel lines, hexagon, circumference, vertex, acute angle, polygon, and many more. Of course, you can easily add to this 21-term list, which is included in two formats: with definitions and without. Introduce kids to shapes in the world using the attached slide show featuring architectural elements. What geometric concepts do they see? There is an interactive quiz as well as games to reinforce the terms. Then, groups take photographs around campus displaying as many of the words as possible. They create a slide show and present it to the class. If you don't have PhotoStory, PowerPoint will work just fine.
Explore symmetry, in this geometry lesson. View "Line Symmetry," an interactive lesson, fold cutout shapes to find the line of symmetry, and record real objects in the classroom that exhibit a line of symmetry.
Tenth graders explore the basic functions of Cabri, Jr. In this geometry lesson, 10th graders practice using the basic functions of the software, including use of the Pointer, Point, Line, Measure, and Construct toolbars.
Tenth graders explore parallel lines cut by a transversal. In this geometry lesson plan, 10th graders investigate the measures of the angle pairs formed when parallel lines are cut by a transversal. The use of technology allows the student to manipulate the construction and measure the angles to arrive at the correct conjecture.
Students use a number line to assist with their additions. They use a calculator to check for factors. Students are taught factors and multiples. They use array model of multiplication to define meaning. Students develop a wide range of adding, subtracting, multiplying, and dividing strategies.
Ninth graders discuss the concept of hyperbolic geometry. They complete Internet geometry activities and write essays comparing and contrasting hyperbolic geometry to Euclidean geometry.
In this geometry review instructional activity, 10th graders solve and complete 100 various types of problems studied in geometry. First, they find the slope-intercept form of a line passing through two points and parallel to a given line. They also find the length of the leg of a right triangle. in addition, they determine the area of a given quadrilateral.
In this geometric figures review worksheet, 10th graders solve and complete 50 various multiple choice problems. First, they find the coordinates of the vertices when a figure is reflected over a line. Then, students name the theorem or postulate that justifies the congruence illustrated. They also find the slope of a line passing through two given sets of points.
Inform your teaching or use this clip at an independent work station. Basic geometric concepts of point, line, plane, and space are fully defined and exemplified in a straightforward and clear way. This clip is slow enough for note taking and can be stopped if further explanation or examples are needed.
What kind of lines have slopes that are the opposite reciprocal of each other? Parallel lines? No. Parabolas? No. Perpendicular lines? Yes! Watch and listen as the instructor demonstrates how to make these determinations about perpendiculars lines and their slopes.
So you have a transversal line intersecting two parallel lines and you are looking for a value that would make two corresponding angles congruent. You have all the information needed to write an equation to find the value. So write that equation and solve for x.
Line, line segment, segment of a line, what does it all mean? Endpoints, midpoints, names of lines, names of segments. Watch this video and learn the definitions of these terms.
Perpendicular lines intersect to form right angles - four of them to be exact. Vertical angles, congruent angles, 90 degrees each, these are some of the special properties of perpendicular lines. Watch this video to find out a couple more special properties.
This video defines what it means for a line to be tangent to a circle. It also defines the term point of tangency and shows how the radius drawn to the point of tangency is perpendicular to the tangent line.
