A right-angled triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for Trigonometry.[br]The side opposite the right angle is called the hypotenuse. The sides adjacent to the right angle are called legs ..[br]If the lengths of all three sides of a right triangle are integers, the triangle is said to be a Pythagorean triangle and its side lengths are collectively known as a Pythagorean Triple.[br][br]In a right triangle, if one leg is taken as the base then the other is height, so the area of a right triangle is one half the product of the two legs.
