 Dotty paper

 Identify properties of angles and parallel and perpendicular lines, and use these to solve problems.

Year 7 (age 11-12)

L6b: Opposite angles
As above but angles are all multiples of 5 degrees

L6e: Angles in right angles

L6f: Angles in triangles

L6g: Angles in right angles, on a straight line and round a point

 Use Pythagoras' theorem

Year 9 (age 13-14)

L7: Use Pythagoras' theorem
Given the coordinates of points A and B, calculate the length of AB.

L8: Use Pythagoras' theorem
The two points A and B are shown on a grid.

 Right angle triangles: Pythagoras and/or trigonometry

A page of right-angled triangles

Years 9-11 (age 13-16)

L12: Right-angled triangles
Six options: 1. Show two sides 2. The hypotenuse and another side 3. A mixture of sides
4. An angle and the hypotenuse 5. An angle and a side 6. A mixture of angles and/or sides
