How do you find the base of an isosciles triangle with only length and perimiter?
A triangle has three sides and three altitudes. Whatlength are you given ? ! ?If the triangle is standing up in the familiar position where the base is not one ofthe two equal sides, then the perimeter is(one of the equal sides) + (the other equal side) + (the base)If the length you're given happens to be the length of one of the equal sides,then the base is the only one of these three terms that you don't know yet.Do you think you can calculate it now ?
