## Are parallel sides?

Lesson Summary Parallel sides are a unique property of certain shapes. These are **sides that will never meet and are always the same distance apart**. Some shapes that have parallel sides include the parallelogram, the rectangle, the square, the trapezoid, the hexagon, and the octagon.

## How many sides can a triangle have?

three sides Every triangle has **three sides** and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
