The sum of the interior angles of a quadrilateral is _______. 180° 90° 270° 360°
2 answers:
Answer:
360°
Explanation:
Quadrilateral are polygons that have four sides. The sum of internal angle of a quadrilateral is 360°. The quadrilateral are closed shape with four sides. Examples of quadrilaterals are trapezium, rectangle, square, Rhombus and parallelograms.
Every quadrilaterals can be divided into two triangle. The sum of angle in a triangle is 180°. Adding the two triangle angle together , we will get the sum as 360°.
Sum of the interior angle of a polygon = 180(n-2) . In the case of quadrilateral, it has 4 sides. n represents the number of sides of the polygon .
interior angle of a quadrilateral = 180(4-2) = 360°
The image illustrate how the interior angle of quadrilaterals can be sum.
