If no sides of a triangle have the same length, the triangle is called** scalene** (pronounced SCALE-een). And, as you might remember, if the triangle has two sides that are the same length, the triangle is called **isosceles**. Use the markings in each diagram below to decide if * *is isosceles or scalene. Assume the diagrams are not drawn to scale.

Sides with the same markings mean the lengths are the same.
