included angle - the angle that is formed by two sides of a triangle
SSS congruence postulate - states that if three sides of one triangle are congruent to three sides of another, then the triangles are congruent
octagon - polygon with 8 sides
heptagon - polygon with 7 sides
regular - a polygon with that has all congruent sides and congruent angles
acute triangle - triangle with three acute angles
AAS Theorem - states that if two angles and a nonincluded side of one triangle is congruent to two angles and a nonincluded side of another triangle, then the triangles are congruent
convex polygon - a polygon where none of the diagons in the polygon are on the outside of the figure
corollary to base angles theorem - states that if a triangle is equilateral, then it is equiangular
n-gon - polygon with n sides
base angle - the angles of an isosceles angle opposite the legs
equiangular - a polygon where all angles are congruent
isosceles triangle - triangle with at least two congruent side lengths
exterior angle theorem - states that the measure of an exterior angle in a triangle is equal to the sum measures of the two non adjacent interior angles
right triangle - triangle with one right angles
