Congruent Triangles

Front

What are congruent triangles?

Back

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

Front

What does AAS stand for in triangle congruence?

Back

Angle-Angle-Side; a method to prove triangles are congruent by showing two angles and a non-included side are equal.

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side; a method to prove triangles are congruent by showing all three sides of one triangle are equal to the three sides of another.

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle; a method to prove triangles are congruent by showing two angles and the included side are equal.

Front

What is the relationship between congruent triangles?

Back

If two triangles are congruent, all their corresponding sides and angles are equal.

Front

How can you determine if two triangles are congruent using angles?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are congruent (AAS or ASA).

Front

What is a scalene triangle?

Back

A triangle with all sides of different lengths and all angles of different measures.

Front

What is an isosceles triangle?

Back

A triangle with at least two sides of equal length and at least two angles of equal measure.

Front

What is an equilateral triangle?

Back

A triangle with all three sides of equal length and all three angles equal to 60 degrees.

Front

What is the significance of corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal, which helps in proving triangle congruence.
