A pair of compasses is a tool which can be used to draw circles and arcs. A pair of compasses is sometimes referred to just as a compass.

The radius is any line segment that joins the centre of a circle to any point on its circumference.

If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.

An arc is part of a curve. An arc of a circle is part of the circle’s circumference.

Drawing the plan and elevations of a solid

Drawing the solid from the plan and elevations

Problem solving with plans and elevations

In the prior unit, pupils considered different views of a 3-D shape in order to understand how to calculate the surface area and volume. In this unit, pupils will be considering a 3-D shape from different viewpoints in order to draw the side and front elevations as well as the plan.

In this unit, pupils will be considering a 3-D shape from different viewpoints in order to draw the side and front elevations as well as the plan view.

Plans and elevations

Isometric means distances between points stay the same. In this lesson we use isometric paper which has equally spaced dots or points.

A solid is a shape that has three dimensions (e.g. width, height and depth).

The plan of a solid is the view of it from above.

The front elevation of a solid is the view of it from the front.

The side elevation of a solid is the view of it from the side.

Isometric means distances between points stay the same. In this lesson you may use isometric paper which has equally spaced dots or points.
