We note that now we have four right triangles. Let’s examine ABE. Since the diagonals of the rhombus bisect each other, each leg of AWe note that now we have four right triangles. Let’s examine ABE. Since the diagonals of the rhombus bisect each other, each leg of ABE is half the length of each diagonal; therefore the legs of ABE are 6 in. and 8 in. See Figure G.50(b). (We note that all four triangles are congruent to each other since they each have the same-size legs, and all sides of a rhombus are equal.) The side of the rhombus is the potenuse of ABE. We label the hypotenuse x and use the Pythagorean theorem to find it:BE is half the length of each
