One of many attributes or properties of a rhombus is that the diagonals are perpendicular bisectors of each other: Knowing this makes the measure of angle AED = 90
Answer:
Is important to remember that the reflection of the point (a,b) across the y-axis is the point (-a,b).
Our original equation is
And after the reflection respect x we got:
