This worksheet is designed to provide scaffolding for learners to aid in recognising and finding equations of perpendicular lines.

Section A asks learners to find the pairs of perpendicular lines from their equations.

Section B wants learners to write the equation of a line perpendicular to another through a given y-intercept.

Section C presents a line on a grid and wants a line perpendicular line equation through a given point.

Section D gives an equation and asks for a perpendicular line through a given point.

Section E wants a line perpendicular to another through two other points.

Section F is similar to section E, but the points are displayed on a coordinate grid.

A final extension question asks learners to find the equation of a perpendicular bisector of two coordinates.
