Geometry problems on the coordinate plane

You are familiar with the ideas of slope and distance on the coordinate plane. You also feel comfortable with congruence an similarity and many of the other core ideas in Euclidean geometry. In this, tutorial, Descartes and Euclid are forced to work together as we tackle geometry problems on the coordinate plane!

Distances between points

We are now going to leverage our understanding of the coordinate plane to think about distances between points and ratios of lengths of segments between points.
