A geometry video explains how to solve for midpoint, length of a line, and use the Pythagorean Theorem. It includes multiple guided practice problems for all three equations.

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.

Break down interior and exterior angles with this video. Using a pentagon, a teacher demonstrates how to find the interior and exterior angles of a polygon. She goes on to explain a few of the properties of these angles, writing down all...

Two figures are congruent if they have the same size and shape. Line segments can also be congruent if they are of the same length. Vertical angles created by intersecting lines are always congruent. Polygons that have matching angles...

Learn how to use an algebraic formula to find the distance between two given points on a coordinate plane.

The midpoint of a line segment can be found using the ordered pair of each endpoint and dividing by 2. Not sure what that means? Watch this video to see the graph of a line segment and see how the teacher uses a formula to find the...

What makes a figure a polygon? Does it have three or more sides? Is it a closed figure? If the answer is yes to both of those questions then it's a polygon. But wait! Some of these polygons have special names based on the number of sides...

Two figures are congruent if they have the same size and shape. Line segments can also be congruent if they are of the same length. Vertical angles created by intersecting lines are always congruent. Polygons that have matching angles...

You've been given two coordinate points on a graph. When these points are connected they form a line segment. Now you have to find the midpoint of this line. Of course there is a formula and all you have to do is plug in the coordinate...

A simple video on how to identify the endpoints of a line segment. Have your class watch this video to clarify any confusions about endpoints. This could be used as extra help for learners who are having difficulty, or as a supplement to...
