Question

In rhombus ABCD, the diagonal line AC and line BD intersect at E. If AE=5 and BE = 12, what is the length of line AB?

Answer 1

...Property: The diagonals of a rhombus are perpendicular

AEB right triangle in E

We apply the Pythagorean theorem

AB²=AE²+EB²

AB²=5²+12²

AB=√169=13

length of line AB = 13
