Let X be any point within a square ABCD. On AX a square AXYZ is described such that D is within it. Which one of the following is correct?
Elementary MathematicsGeometry
- AAX = DZ
- Bangle ADZ = angle BAX
- CAD = DZ
- DBX = DZ
Explanation
A 90-degree rotation about A sends B to D and X to Z, so segment BX maps onto segment DZ.
