Step-by-step explanation:

triangle is a polygon formed by any three non-collinear points on a plane having three sides and corresponding three angles. The sum of all angles in a triangle is equal to 180 degrees. In a triangle, the side opposite to the smallest angle is the shortest and the side opposite to the largest angle is the largest side.

If one angle of a triangle is a right angle, then the triangle is called a right triangle. The largest side of a right triangle is called the hypotenuse.
