Tangent
These are the lines that bisect each other in a square, rectangle, or rhombus.
Diagonals
Line that cuts through two parallel lines.
Transversal
This can be used to find the length of a side of any shape (besides a circle).

This is the name for points on the same line.
Collinear
The process used to find the equation of a circle.
