Front

If two triangles have two angles and the included side equal, what can be said about their congruence?

Back

They are congruent by ASA (Angle-Side-Angle) Postulate.

Front

What is a scalene triangle?

Back

A triangle with all sides of different lengths.

Front

What is an isosceles triangle?

Back

A triangle with at least two sides of equal length.

Front

What is an equilateral triangle?

Back

A triangle with all three sides of equal length.

Front

What does the SAS postulate state?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What does the ASA postulate state?

Back

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.

What does the AAS postulate state?

Back

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