Question 1

base angles (of an isosceles triangle)

Answer 1

The two angles that have the base as part of one side

Question 2

Base angles converse Thm

Answer 2

If two angles of A triangle are congruent, then the sides opposite them (in the same triangle) are congruent

Question 3

Corollary

Answer 3

A Thm that follows easily from another Thm that has been proven already

Question 4

Corollary to base angles Thm

Answer 4

If a triangle is equilateral, then it is also equiangular

Question 5

Corollary to base angles converse Thm

Answer 5

If a triangle is equiangular, then it is also equilateral

Question 6

Hypotenuse-Leg (HL) Thm

Answer 6

If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of a second triangle, then the 2 triangles are congruent
