Determine the radius of a circle that is tangent to 3 sides of the isosceles trapezoid.
The sides of the trapezoid are 'm' for the 2 common side lengths, and 'n' for the smaller, 'p' for the larger bases.
In other words:
I know that the area of a trapezoid is 1/2 h(b1 + b2). I know radius is 1/2 diameter.
Please help. Thanks.
