In this lesson you will discover some properties of rhombuses, rectangles, and squares. What you discover about the diagonals of these special parallelograms will help you understand why these lifts work the way they do.
Recall that a rhombus is a parallelogram with four congruent sides, or an equilateral parallelogram.

To construct a parallelogram that is not a rhombus, you need two double-edged straightedges of different widths.

Most of the paragraph proofs and flowchart proofs you have done so far have been set up for you to complete. Creating your own proofs requires good reasoning strategies and planning. One excellent reasoning strategy is “thinking backward.” If you know where you are headed but are unsure where to start, start at the end of the problem and work your way back to the beginning one step at a time.
A concave kite is sometimes called a dart.
