Calculating Angles in a Quadrilateral

By the end of this unit, children will be able to:

1. Understand the properties of a quadrilateral, including the sum of its interior angles.
2. Apply knowledge of angles to calculate missing angles in various types of quadrilaterals.
3. Use the fact that the sum of the interior angles of a quadrilateral is 360 degrees to solve angle problems.
