What is 3 sided shape with 1 pair of perpendicular lines?

Answer 1

A 3-sided shape with 1 pair of perpendicular lines is called a right triangle. In a right triangle, one of the angles is a right angle, which means it measures 90 degrees. The side opposite the right angle is called the hypotenuse, while the other two sides are called the legs. The perpendicular lines in a right triangle are formed by the legs meeting at a right angle.
