Question

if three angles of a a quadrilateral are equal and the fourth angle is a a right angle then find the three angle of the quadrilateral

Answer 1

Step-by-step explanation:

Sum of 4 angles is 360

Let x represent one of the three equal angles.

Since one angle is 90, we have

90+3x=360

3x=270

x=90

All angles are 90 degrees. It is a rectangle.
