Today's goal: Classify and use properties of the special parallelograms: rhombi and squares.

Multiple Select

Quick Check: Which of the following is NOT a key characteristic of ALL parallelograms?

Opposite Sides Are Parallel and Congruent

Consecutive Angles Are Supplementary

The Sum of Interior Angles Is >360 Degrees

Opposite Angles Are Congruent

Diagonals Are Perpendicular

Recall:

Diagonals Are Not ALWAYS Perpendicular
Diagonals Do Not ALWAYS Bisect Angles
Consecutive Sides Are Not ALWAYS Congruent

All Rhombi Are Parallelograms...

...But Not All Parallelograms Are Rhombi. Why?
