Question

What is the internal angle sum of a quadrilateral? (Hint: A quadirlateral has 4 sides.) OA) 90 OB) 180 OC) 360 OD 540

Answer 1

The internal angle sum of a quadrilateral is :

C. 360°

The sum of internal angles of a polygon is determined by a formula :

$\longmapsto (n - 2) × 180°$

where n represents number of sides.

In a quadrilateral there are four sides,

So, plugging 4 in the formula :

• $(4 - 2) \times 180°$

• $2 \times 180°$

• $360°$
