Congruent Figures and Congruent Triangles Shortcuts

Front

What are congruent figures?

Back

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

Front

What does it mean when two angles are congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the SSS Congruence Theorem?

Back

The SSS (Side-Side-Side) Congruence Theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the SAS Congruence Theorem?

Back

The SAS (Side-Angle-Side) Congruence Theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the ASA Congruence Theorem?

Back

The ASA (Angle-Side-Angle) Congruence Theorem states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the AAS Congruence Theorem?

Back

The AAS (Angle-Angle-Side) Congruence Theorem states that if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

Front

What is the HL Congruence Theorem?

Back

The HL (Hypotenuse-Leg) Congruence Theorem applies to right triangles and states that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Front

How can you determine if two triangles are congruent?

Back

You can determine if two triangles are congruent by using congruence theorems such as SSS, SAS, ASA, AAS, or HL.

Front

What does it mean if two triangles are not congruent?

Back

If two triangles are not congruent, it means they do not have the same size and shape, and their corresponding sides and angles are not equal.

Front

What is the importance of congruent triangles in geometry?

Back

Congruent triangles are important in geometry because they help in proving properties of shapes, solving problems, and establishing relationships between different geometric figures.
