Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does the AAS congruence rule state?

Back

If two angles and the non-included side of one triangle are equal to two angles and the non-included side of another triangle, then the triangles are congruent.

Front

What is the ASA congruence rule?

Back

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 does the SSS congruence rule state?

Back

If all three sides of one triangle are equal to all three sides of another triangle, then the triangles are congruent.

Front

What is the SAS congruence rule?

Back

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 significance of the statement ∡AED≅∡BEC in a proof?

Back

It indicates that the angles are congruent, which is often a critical step in proving triangle congruence.

Front

How do you find the value of x in a triangle?

Back

Use the properties of triangles, such as the sum of angles in a triangle equals 180 degrees, or apply congruence rules.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint, called the vertex.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is a postulate in geometry?

Back

A postulate is a statement that is accepted as true without proof, serving as a starting point for further reasoning.
