Voronoi diagrams

Question 1

Perpendicular bisector of a line

Answer 1

Find the gradient (m) of the line, inverse it by flipping the symbol (+/-) and making 1/(m)

Find the midpoint (equation (if needed) in data booklet)

Insert the gradient and midpoint coordinates into the point-gradient form

Rearrange the equation to how you’ve been asked to

Question 2

Calculating whether one point is further than another

Answer 2

Use Pythagoras theorem:

a² + b² = c²

The bigger number is further away (duh)
