The Exterior angle theorem is...

• The sum of the angles in a triangle is 180.

• The measure of the exterior angle of a triangle is the sum of the two remote interior angles.

• If three sides in one triangle are congruent to 3 sides in another triangle then the two triangles are congruent.

• If two angles in one triangle are congruent to two angles in another triangle then the triangle and each angle in the triangle are congruent.

What is the definition of the SSS Postulate?

• If two sides of a triangle are congruent then the base angles are congruent.

• Corresponding Parts of Congruent Triangles are Congruent.

• if a traversal interjects parallel lines then the corresponding angles are congruent.

• If three sides in one triangle are congruent to 3 sides in another triangle then the two triangles are congruent.

What does CPCTC stand for?

• Corresponding Parts of Congruent Triangles are Congruent.

• If the hypotenuse and leg of one triangle and the leg of another triangle then the triangles are congruent.

• If two sides of a triangle are congruent then the base angles are congruent.

• If a point is on the angle bisector, then the point is equidistant from the sides of the angle.
