Answer:
The sum of the interior angles of a quadrilateral <u>equals</u><u> </u> the sum of its exterior angles.
Step-by-step explanation:
The sum of the exterior angles of a quadrilateral is 360 degrees.
The sum of the interior angles = (n-2)*180
Here n = 4, the number of sides.
Quadrilateral has 4 sides.
The sum of the interior angles = (4 - 2)*180
= 2*180
= 360 degrees.
Therefore, the sum of the interior angles of a quadrilateral <u>equals </u> the sum of its exterior angles.
