Angle Facts

In this lesson, we will calculate the missing angles around a point and on a straight line. We will revisit the properties of angles on a straight line and a point, and use this information to help us deduce the value of missing angles in problems.

In this lesson, we will calculate the missing angles in a triangle. We will revisit the properties of angles in a triangle and angles on a straight line to help us deduce the value of missing angles in problems.

In this lesson, we will calculate the missing angles in a quadrilateral. We will revisit the properties of angles in a quadrilateral to help us deduce the value of missing angles in problems.

In this lesson, we will calculate the missing angles in a trapezium, parallelogram and a kite. We will revisit the properties of these quadrilaterals in order to help us deduce the value of missing angles in diagrams.
