Question

5. The four angles of a quadrilateral are equal. Find the measure of each angle.​

Answer 1

Answer:

(｡♡‿♡｡)

Let the measure of each of the other two angles be . In a quadrilateral, the sum of all four angles is 360°. Therefore, each equal angle of the quadrilateral measures 80°.

Answer 2

Explanation:

ABCD is a quadrilateral having all four angles equal.

Let each angle be x

We know sum of measure of all four angles of quadrilateral is 360

o

.

∴ ∠A+∠B+∠C+∠D=360

o

⇒ x+x+x+x=360

o

⇒ 4x=360

o

⇒ x=90

o

∴ The measure of angles of quadrilaterals are 90 , 90,90,90.
