What do we call all of the points that follow a set rule?
Loci
What shape are the points that are all equidistant from a single point?
A circle
What shape do the points equidistant from two points make?
A straight line
What does the loci of a circle represent?
All of the points equidistant from a central point.
When drawing loci how do you specify which area you have chosen?
Shading and clear labels
What does bisect mean?
Divide into two equal sections
What does perpendicular mean?
Two lines which meet at right angles.
To perpendicularly bisect a line, the compass must be open to what length?
More than half of the length of the line.
What tools are needed when drawing a construction?
Compass, pencil or pen and ruler
How can you use constructions to create a 45 degree angle?
Bisect a line, then bisect that angle.
List the four types of shape transformation

What information do you need to describe a translation?
A vector
What information do you need to describe a rotation?
An angle, direction and centre of rotation.
What two things do you need to list when describing an enlargement?
The centre of enlargement and scale factor.
What vector is used to translate a point 5 units right and 2 units down?
5 on the top, -2 on the bottom, all in a big bracket
