Worksheet Overview

This activity is about finding the angles in a quadrilateral, which always add up to 360°.




angles in a quadrilateral


To find angle x, we add up the existing angles and subtract this from 360°.


We can see that the quadrilateral above has two right angles and a third angle of 34°.


90 + 90 + 34 = 214

x = 360 - 214 = 146°
