base angles of an isosceles triangle
In an isosceles triangle, the two angles that have the base as a part of one side are the base angles
base angles theorem
if 2 sides of a triangle are congruent, then the angles opposite them are congruent.
base angles converse theorem
If two angles of a triangle are congruent, then the sides opposite them are also congruent
corollary to base angles (and converse) theorem.
If a triangle is equilateral, it is also equiangular, and if a triangle is equiangular, then it is also equilateral
hypotenuse leg congruence theorem
If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and leg of a second right triangle, then the two triangles are congruent.
