Periodic Billiard Paths in Triangles
... Let a point move on a frictionless plane bounded by a triangle If it hits a corner (a vertex), then it stops If it hits a side (an edge), then it changes its direction such that the angle of reflection is equal to the angle of incidence The path that the point follows is called a billiard path An in ...

Grade 7 Mathematics Module 6, Topic B, Lesson 14
... In contrast to Lesson 12, where students had to examine pairs of distinct triangles, the diagrams of triangles in Lesson 13 are presented so that a relationship exists between the triangles due to the way they are positioned. They may share a common side, may be arranged in a way so that two angles ...
