There are three basic types of triangles. Equilateral triangles have three congruent (equal) sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the two angles opposite those sides are also congruent. Scalene triangles have no congruent sides or angles. Right triangles are another type of triangle and they have one ninety-degree angle. Right triangles can either be scalene or isosceles.

Can Pythagorean Theorem be used on all types of triangles?
No it can only be used with right angle triangles.
What types of triangles have at least two acute angles?
All triangles need at least two acute angles
Are all the triangles similar?
No because there are different types of triangles but they all have 3 sides and 3 inside angles that add up to 180 degrees
What is a triangles isosceles or a scalene?
They are both types of triangles
Are triangles equilateral?
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
