In order to answer that, I need to know the position of ABCD with respect tothe x-axis before the reflection process begins.But wait! What light through yonder window breaks ? ! On second thought, maybe I don't.If D is the point (x, y) before the reflection, then D' is the point (x, -y) after it.

Ah, what a delightful shape a rhombus is, with all its equal sides and angles! To find the measure of angle AEB, we simply divide the total of 360 degrees by the four equal angles of the rhombus. That means angle AEB in rhombus ABCD is 90 degrees, creating a perfect corner for our happy little shape.

it is a right triangle because a rhombus' diagonals are perpendicular

A rhombus has two lines of symmetry. They are also called its diagonals. Suppose there is a rhombus ABCD AC and BD are its lines of symmetry.
