What is a segment starting at a vertex and going to the opposite side AND meeting at a right angle?
Name the 3 properties that the diagonals of a rhombus have.
diagonals bisect each other diagonals are perpendicular diagonals bisect the angles
If a rectangle and a rhombus had a child, what would it look like? Why?
It would be a square b/c a square has all of the properties of a rectangle and a rhombus.
Sometime the coordinate plane is referred to as the Cartesian Plane. It was invented by this man.
