What Are Congruent Figures Explained - What Is Congruent? - What Are Corresponding Angles And Sides?

Описание: In this video we discuss what are congruent figures. We go through the marks and symbols that are used to show congruency, and list corresponding angles and corresponding sides

Transcript/notes
Two or more figures are congruent if they have the same shape and size. For instance, here are 5 congruent figures and here are 5 non congruent figures.

When 2 figures are congruent, their corresponding angles are congruent, and their corresponding sides are congruent. For instance, here are 2 congruent figures. The tick marks and arc symbols with tick marks show which sides and angles are congruent.

We use this symbol, an equals sign with a tilde above it to signify congruence. So, we would say figure DEFG is congruent to figure QPRS, and when we write this, we list the corresponding vertices or angles in the same order.

Here is a listing of the corresponding angles and corresponding sides.

Since these figures are congruent, this also means that the corresponding angles are equal, and the corresponding sides are equal. Understanding these principals will help when we need to find certain values of certain figures as you see here, and I will cover this in depth in a future video.
