Pupil outcome: I can describe rotations using the standard unit of degrees when compared to a right angle. Key learning points: - Some objects rotate or spin and this is measured in degrees - Rotation can be more than a right angle >90...

Pupil outcome: I can describe static angles using the standard unit of degrees when compared to a right angle. Key learning points: - There are 90 degrees in a right angle - Acute angles are between 0 and 90 degrees - Obtuse angles are...

Pupil outcome: I can rotate objects using information about centre, size and direction of rotation Key learning points: - Tracing paper can be a helpful tool to perform a rotation. - The image and the object should be congruent. - Unless...

Pupil outcome: I can interpret pie charts. Key learning points: - Knowing the angle size for a sector allows calculation of the frequency. - By knowing the total, statements can be made comparing the data. - Different pie charts may have...

Pupil outcome: I can understand the size and direction of rotation. Key learning points: - Rotations can be either clockwise or anti-clockwise. - The size of the rotation is given in degrees.

This is the first of several videos about the Unit Circle. In this video, we will define the unit circle and fill in the radians and degrees. This video explains how to DERIVE the unit circle, but not necessarily how to use it.

How to solve problems with bearing using trigonometry. Bearing is often used as a way of describing direction in sailing and navigation. Once you know the basic definitions and some trigonometry, you can use bearing to find direction and...
