Geometry lessons - School Yourself Essential stuff for describing the world around you 1 Lines and angles 2 Related angles What about angles bigger than 360 degrees? 3 Triangles See if it's really true, and then prove it! They have two equal sides, but what about their angles? In triangles, sides and their opposite angles are related! 4 Triangle congruence and similarity
