The internal angle sum of a quadrilateral is :
C. 360°
The sum of internal angles of a polygon is determined by a formula :
[tex] \longmapsto (n - 2) × 180° [/tex]
where n represents number of sides.
In a quadrilateral there are four sides,
So, plugging 4 in the formula :
- [tex](4 - 2) \times 180°[/tex]
