1st ESO ART. Unit 7.1 Drawing perpendicular lines with compass and setsquare

We can use setsquares to draw horizontal, vertical and oblique lines by holding one of them in position and rotating the other above it.

We can also draw more complex figures using the compass and setsquare. Let start with the basic perpendicular figures.

Perpendicular to a segment at its endpoint



Perpendicular to a straight line through a point that is external to it
