Isosceles (triangle)

has (at least) two sides of equal length.

Apex

The Highest Point

Base angles

are equal.

meets the base at right angles and bisects the apex angle.

Median (The line joining the apex to the midpoint of the base)

Legs

in a right triangle, the sides that include the right angle; in an isosceles triangle, the pair of congruent sides

Base

the number that is written with an exponent

vertex angle

the angle in-between the two congruent sides (legs) of the triangle

Isosceles Triangle Theorem

If 2 sides of a triangle are congruent, then the angles opposite those sides are congruent

Converse of the Isosceles Triangle Theorem

If 2 angles of a triangle are congruent, then the sides opposite those angles are congruent.

Corollary to the Isosceles Triangle Theorem

If a triangle is equilateral, then the triangle is equiangular.

Corollary to the Converse of the Isosceles Triangle Theorem

If a triangle is equiangular, then the triangle is equilateral.
