A parallelogram is a quadrilateral with two pairs of parallel and equal sides.

Any parallelogram can be decomposed and the parts rearranged to form a rectangular parallelogram

Maths

In this unit pupils will use knowledge of shape properties to draw, sketch and identify shapes  In the future unit pupils will explain how to calculate the area of a parallelogram and a triangle and describe the relationship between scale factors and side lengths of two shapesThey will describe positions in all four quadrants drawing and translating simple shapes and reflecting them in the axes

In the prior unit pupils compared the size of angles with a clear visual difference and use the terms acute obtuse and reflex when describing the size of angles or amount of rotation with relation to right angles using a unit called degrees In this unit pupils will use knowledge of shape properties to draw, sketch and identify shapes

Draw, compose and decompose shapes

A rectangular parallelogram has been formed.

A new non-rectangular parallelogram has been formed.

The triangles have been cut off the ends of a parallelogram and repositioned. Which of the statements is true? 

The parallelogram is cut along the marked line. Complete. The parallelogram has been decomposed into a triangle and a {{ }}.

can be turned into a rectangle by cutting two triangles off and repositioning.

can be turned into a rectangle by moving one of the triangles to the other side.

cannot be turned into a rectangle, unless it is already one. 

Which of these statements are true? A parallelogram….

A parallelogram and a rectangular parallelogram can have the same area.

A parallelogram and a rectangular parallelogram cannot have the same area.

Adding a triangle to a parallelogram can give it the same area as a rectangle.
