There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.
Answer: 2 Explanation: A parallelogram is a quadrilateral which has both pairs of the opposite sides parallel. Congruent triangles are triangles that have exactly the same three sides and exactly the same three angles. So, in a parallelogram, each diagonal divides it in 2 congruent triangles.

Equilateral triangles have three congruent sides and three congruent angles
3 because equilateral triangles are triangles that have 3 congruent sides.
Only if the congruent angle is the angle between the two congruent sides (SAS postulate).
