The meaning of the word congruent is very similar to being equal, and it is often used in geometry in reference to side lengths and angle degrees. The instructor uses a document camera to explain this concept.

During a museum tour, Grandpa Bloop notices that the triangle on display and the triangle in the picture are not the same. However, he does notice they share similar traits. This video could be used to introduce a lesson on similar/congruent traingl...es. ( 1:28)[more]

There is a lot of information on the screen in this four-minute video clip about similar and conguent solids. The viewer may wish to open the video to 'full screen' to see everything fully.

This ten-minute video is part of a series. This video shows how to
prove triangles congruence with sss-all sides congruent. sas-two sides are the same and the angle between them aas-two angles and one side are congruent asa- two angles congruent an...d a side between them. Video may start with an ad. (10:14)[more]

Identify the properties of two-dimensional geometric figures using appropriate terminology and vocabulary. Draw two congruent geometric figures. Identify corresponding parts of congruent polygons as congruent. Draw a model that demonstrates basic geo...metric relationships such as parallelism, perpendicularity, similarity/proportionality, and congruence.[more]
