How do you find the perpendicular height of a isoceles triangle?
You can find it by using the Pythagorean theorem if you know the side and the base of triangle. In an isosceles triangle the median is also the altitude. The formula is: (The measure of the side length)^2 – (The measure of the one half of the base length )^2 = (The measure of the altitude)^2. Find the square root of the result that you’ll have the measure of the altitude.
