Rhombuses, Rectangles, & Squares
Rhombuses
I have constructed rhombus ABCD for you.
Using the "Move" tool, drag vertices A, B, & D to check that the shape remains a rhombus.
Draw in the diagonals of the shape.
Using the "Angle" tool, measure different angles that we have NOT already talked about with parallelograms. What do you notice?
Rectangles
I have constructed Rectangle PQRS.
Move vertices P, Q, & R to make sure the shape stays a quadrilateral.
Draw in the diagonals. Using the "Distance or Length" tool, find a property that we have not yet discovered.
