WebExample 2: Find the fourth angle of the right trapezium if one of the given angles is 60°. Solution: As we know, in a right trapezium, there are 2 right angles and the sum of all the interior angles in a trapezium is always 360°. So, if one of the given angles is 60°, let the missing angle be x°. The fourth angle can be calculated as x° + 90° + 90° + 60° = 360°. WebGiven a trapezoid ABCD with parallel sides AB and CD.
