- Angles of a Quadrilateral
When three angles are shown and the fourth is wanted, what supports the work is 360 degrees, the sum of the four angles. General quadrilaterals rather than trapezoids alone are lined up, and questions finding an exterior angle where a side has been extended are solved as Calculation as well.

A question about an exterior angle needs the remaining interior angle first and a second tier that subtracts it from 180 degrees. Papers appear where the interior angle from the first tier was copied straight into the answer box, so if the answer added to the interior angle beside it makes 180 degrees, the second tier was reached.
All that changes from Angles of a Triangle is the sum being leaned on, 180 degrees becoming 360 degrees. The procedure itself does not move. Angles of Polygons, where the count of angles rises further, waits at the end of the unit.
