Describe why you have to be careful when talking about the following words
A compass
There are two compasses
A pair of compasses
There are at least six different types of polygons (excluding polygon names such as hexagon etc.). Find out about these. Pictures should be included in your research too..
Shapes with names ending in “…gon” such as a pentagon are two dimensional shapes
Shapes with names ending in “….hedron” such as Octahedron are three dimensional shapes

Always / Sometimes / Never:
to draw a triangle you need to know the size of three angles; to draw a triangle you need to know the size of three edges. Explain your thoughts
Convince me that a hexagon can have rotational symmetry with order 2.
Describe how would you explain to someone what the smallest possible order of rotational symmetry could be for any 2D shape.
1. Name the shape ABCDEF
2. Name a line segment that could be drawn on the shape to show a line of symmetry
3. Name the polygon that has two more edges than shape ABCDEF
4. What is the order of rotational symmetry of shape ABCDEF?
5. Draw accurately the shape ABC with the lengths all being doubled from those shown on this homework; and name the shape ABC too.
6. Name the shape ADEF.
7. Use the correct notation to identify a right angled triangle that could be cut out of the shape above.
8. Name two line segments that could be drawn on the above shape that would be perpendicular to each other
