# G2c – Mixed loci problems

This is the students’ version of the page. Log in above for the teachers’ version.

# A starting point

#### A fixed distance from a point

Drag the red point so that it is 5 m from A. The point will turn blue when you have done so, and it will leave a blue mark on the canvas. Move the point to different position that is also 5 m from A. Keep doing this. Try to drag the point along all the possible locations that are 5 m from A:

#### Equidistant from two points

Drag the red point so that it is the same distance away from A and B. The point will turn blue when you have done so, and it will leave a blue mark on the canvas. Move the point to different position that is also equidistant from A and B. Keep doing this. Try to drag the point along all the possible locations:

#### A fixed distance from a line segment

Drag the red point so that it is 5 m from the line segment AB. The point will turn blue when you have done so, and it will leave a blue mark on the canvas. Move the point to different position that is also 5 m from AB. Keep doing this. Try to drag the point along all the possible locations that are 5 m from AB:

# Mixed loci problems

This lesson is different from most BossMaths lessons. It only contains worked examples, diagnostic questions, exam-style questions and a challenge. The worksheet (available under Teacher resources to registered schools only) is required for this lesson, as the diagrams are formatted to print at the appropriate size on A4 paper.
