All the angles of a quadrilateral are equal to each other. Find the measure of each. Is the quadrilateral a parallelogram? What special type of parallelogram is it?

Explanation

Let all the angles be `x^@`
`x + x + x + x = 360...........`(Angle sumproperty)
`4x = 360`
`x = 90^@`
Therefore, measure all the angles is `90`
It can be a square or rectangle, because rectangle and square has all its angles as` 90`.
