find the area of the isosceles triangle with side lengths 14 inches,25 inches,and 25inches
================
An isoceles triangle can always be made into 2 congruent right triangles with an altitude from the vertex of the 2 equal sides to the 3rd side.
In this case, it makes two right triangles with sides of 7, 24 & 25.
Area of each = b*h/2 = 7*24/1 = 84 sq inches
Total area = 168 sq inches.
