Unit Summary
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.
Lesson Summary
You will learn to accurately construct circles and triangles using a pair of compasses and protractor respectively.
Key Notes
- A pair of compasses can be used to draw a circle with a particular radius.
- A ruler and protractor can be used to accurately draw a triangle given enough information.
- A ruler and a pair of compasses can also be used to accurately draw a triangle where the side lengths are known.
Vocabulary To Learn
- Pair of compasses: 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.
- Radius: The radius is any line segment that joins the centre of a circle to any point on its circumference.
- Congruent: If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.
- Arc: An arc is part of a curve. An arc of a circle is part of the circle's circumference.
Common Mistakes To Avoid
- Pupils read from the incorrect values on the protractor.
