The formula for area of a right triangle … In the first, two angles and a side are known. An isosceles triangle is a special case of a triangle where 2 sides, a and c, are equal and 2 angles, A and C, are equal. For example, if the sides are 3 in, 4 in, and 5 in, then the perimeter is simply 3 + 4 + 5 = 12 inches in total. Easy to use calculator to solve right triangle problems. Isosceles triangle Calculate the area of an isosceles triangle, the base of which measures 16 cm and the arms 10 cm. The height of the triangle corresponds to its base, so whenever base length changes, height also changes. Perimeter of Isosceles Triangle: P = a + b + c = 2a + b, Semiperimeter of Isosceles Triangle: s = (a + b + c) / 2 = a + (b/2), Area of Isosceles Triangle: K = (b/4) * √(4a. Finding the missing side of a right triangle is a pretty simple matter if two sides are known.
