17 What is 67?

18 T/F: Two triangles are congruent if two sides and an angle of one are congruent to two sides and an angle of the other.

19 What is False?

20 If the sum of two angles is 90 then the angles are complementary. Form the converse and write a biconditional if appropriate.

21 What is… If two angles are complementary, then the sum of the two angles is 90. Two angles are complementary if and only if the sum of the two angles is 90.

22

23 What is the symmetric property of congruence?

24 Every median for this triangle is also an angle bisector.

25 What is an equilateral triangle?

26 If an angle bisector of a triangle is also perpendicular to the side opposite the angle, then the triangle is ____.

27 What is isosceles?

28 T/F: Supplements of congruent angles are congruent.

29 What is True? This is the supplement theorem.

30 Ray AP bisects < BAC. AC = AB. Points C, P, and B are noncollinear. Prove PC = PB.
