C Program for Beginners : Area of Square Shape : Square Formula : side * side Definition : A plane rectangle with four equal sides and four right angles A four-sided regular polygon You can compute the area of a square if you know the length of its sides Program : [crayon-5e1a9eff6809c909457067/] Output : […] For any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the two other sides. It follows that any triangle in which the sides satisfy this condition is a right triangle. There are also special cases of right triangles, such as the 30° 60° 90, 45° 45° 90°, and 3 4 5 right triangles ... Mar 18, 2014 · The area of right triangle is 84 square feet and its hypotenuse is 25 feet. The area of right triangle is A = 1/2 base * height.. Let x be the base (adjacent side) and y be the height (opposite side) of the right triangle. sides and a parallelogram is a quadrilateral with parallel opposite sides, etc. Triangles A triangle is a closed ﬁgure composed exactly of three line segments called the sides. The points of intersection of any two line segments is called a vertex. Thus, a triangle has three vertices. Aslo, a triangle has three inte-rior angles. See Figure 37.4(a).
