What is the SAS postulate in triangle congruence?

Back

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

What is the SSS postulate in triangle congruence?

Back

The SSS (Side-Side-Side) postulate states that if all three sides of one triangle are congruent to all three sides of another triangle, then the two triangles are congruent.

What does it mean for line segments to be congruent?

Back

Line segments are congruent if they have the same length.

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is the AAS postulate in triangle congruence?

Back

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