Area of an Isosceles Triangle. Consider the triangle
Chapter 7, Problem 61(choose chapter or problem)
Area of an Isosceles Triangle. Consider the triangle below, where the vertex angle measures the equal sides measure a, the height is h, and half the base is b. (In an isosceles triangle, the perpendicular dropped from the vertex angle divides the triangle into two congruent triangles.) The two triangles formed are right triangles.In the right triangles, and Multiply each side of each equation by a to getThe area of the entire isosceles triangle isSubstitute the values for b and h into thearea formula. Show that the area is equivalent to
