A character or quality that something has.

Identify properties of triangles

Maths

Make different sized angles by rotating two lines around a fixed point

Identify and describe right angles

Know that a right angle describes a quarter turn

Identify properties of quadrilaterals

Know that a rectangle is a four-sided polygon with four right angles

Know that a square is a rectangle in which the four sides are of equal length

Investigate the shapes made when rectangles are cut on the diagonal

Join four right angles at a point using different right-angled polygons

Investigate and draw other polygons with right angles

In this unit pupils will rotate two lines around a fixed point to make different sized angles. They will identify vertices. In the future unit pupils will investigate ways to compose and decompose polygons. They will investigate quadrilaterals with and without parallel and perpendicular sides.

In the prior unit pupils ordered and arranged combinations of objects in patterns and sequences. They consolidated understanding of whole, half, quarter and three-quarter turns, in terms of right angles, using mathematical vocabulary to describe position, direction and movement. In this unit pupils will rotate 2 lines around a fixed point to make different sized angles. They will identify vertices

In this unit pupils will rotate 2 lines around a fixed point to make different angles. They identify vertices and describe half, quarter and three-quarter turns in terms of right angles.

Right angles

The corners of a shape are called the {{ }}.

Which of these statements are true for all triangles?

Which triangle is exactly the same size and shape as shape a)?

Which triangles have at least two sides the same length?

Which of these images shows a right angle?

A right angle is the same as a {{ }} turn. 

How many right angles does this shape have?

Look at this triangle. Which of these statements are true?

Which letter does not have at least one right angle?

Which shapes have at least one right angle?
