What does AAS stand for in triangle congruence?

Back

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

What is the SAS postulate?

Back

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

What does it mean if two triangles are 'Not Congruent'?

Back

It means that the triangles do not have the same size and shape, and there is no postulate that can prove their congruence.

If a triangle has sides of lengths 8 yd, 10 yd, and 6 yd, what is its perimeter?

Back

The perimeter is 8 yd + 10 yd + 6 yd = 24 yd.

What is the formula for finding the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. To find a missing angle, subtract the sum of the known angles from 180 degrees.

If two angles in a triangle measure 60 degrees and 50 degrees, what is the measure of the third angle?

Back

The third angle measures 180 - (60 + 50) = 70 degrees.
