WebbGiven the side lengths of an isosceles triangle, it is possible to solve the perimeter and area using a few simple formulas. Find the Perimeter. You can find the perimeter of an isosceles triangle using the following formula: p = 2a + b. Thus, the perimeter p is equal to 2 times side a plus base b. Find the Semiperimeter WebbA right triangle (American English) or right-angled triangle (British) is a triangle in which one angle is a right angle (90°). A right triangle is a triangle having two perpendicular sides. Properties of a triangle A triangle has three sides and three angles. The sum of the angles (internal angles) of a triangle is always 180 degrees.
