Triangles and Transformations

If a triangle has 3 congruent sides it is:

• Equiangular

• Isosceles

• Equilateral

• Scalene

The triangle angle sum theorem states that the sum of the three angles of a triangle equal ______ degrees.

• 180

• 90

• 270

• 360

The two congruent sides of an isosceles triangle are called the:

• base

• equilateral

• legs

• vertices

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