Construct Perpendicular Lines

In this sketch students will be shown the steps to create two perpendicular lines. Then they will use the method to bisect an angle to create a 45`^o` angle. The idea is that they will do the steps digitally here and then repeat them physically with a ruler and a compass. Note that within Desmos there are already tools to create perpendiculars. The purpose here is to not use that tool but to instead use only the tools that would be available physically (ie a ruler and compass). There are also specific instructions on each slide for the steps when using a ruler and a compass. Students should have done the bisection activity first. https://teacher.desmos.com/activitybuilder/custom/5ac66b014d65ca467df837a7
