Isosceles Triangle
Triangle with two congruent sides
Base angles theorem
two sides of a triangle are congruent iff the angles opposite them are congruent
Equilateral triangle theorem
A triangle is equilateral iff it is equiangular (all 60*)
Equilateral
All angles =60*
Hypotenuse Leg
If the hyp. and leg of one triangle are congruent to the hyp. and leg of another triangle, the two triangles are congruent
Angle Side Angle
If two angles and the included side of a triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent
Angle Angle Side
If two angles and the non-included side of a triangle are congruent to two angles and the non-included side of another triangle, then the two triangles are congruent
Simplified base angles theorem
base angles of two Isosceles triangles are congruent
CPCTC
Corresponding part of congruent triangles are congruent
Side angle side theorem
If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent
