    Given: Angle ACB is a right angle; D, E, and F are the midpoints of Seg. AB, BC, and CA. Find CD, EF, ED. Please help me understand how to do this

    Sorry, I didn't realize you don't know trig. In this case, use the Pythagorean theorm

    FE would be 13.

    Or, you could have used proportions. Since every triangle is the midpoint of another.

    But since you don't know trig, I don't know how to explain this to you using any ordinary method.
