Section 4.3 - Isosceles and Equilateral Triangles
Isosceles Triangle
2
Base angles theorem - if a triangle is isosceles
then the base angles are congruent
Converse of the base angles theorem - if 2 angles
of a triangle are congruent then the triangle is
isosceles
3
Equilateral theorem - if a triangle is
equilateral then it is equiangular Equian
gular theorem - if a triangle is equiangular then
it is equilateral
All angles of an equiangular triangle 600
