Congruent Figures5

Congruent figures are shapes that are identical in form and size. They can be superimposed on each other.

Two angles are congruent if they have the same measure.

The measures of ∠P and ∠T are equal.

Two triangles are congruent if their corresponding sides and angles are equal.

The symbol for congruence is '≅'.

The measure of ∠J is 59°.

Corresponding parts of congruent figures are equal.

x represents a side length or angle measure in the triangle.

The SSS postulate states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

The ASA postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.
