# What type of Parallelogram is THAT?!

There are occasions when you just gotta know what type of parallelogram you're dealing with. Is it a square? A rectangle? A RHOMBUS?! Or maybe even just a plain parallelogram? Let us find out....

Congruent means equal, but not always...remember in a geometric proof, congruent and equal are not the same. A 45-45-90 triangle is a triangle in which two angles are 45 and one is 90. If I made any errors or left anything out, let me know!

1. Before you can tell what type of parallelogram your polygon is, we must know: Is it even a polygon?
2. Ok, we know this is a polygon. Now we have to make sure this is a quadrilateral. Well, is it?
3. Ok, we know this is a quadrilateral. Just one more thing to check before the real fun begins, k? Is it even a Parallelogram?
4. Alright! It is indeed a parallelogram!
5. Opposite sides:
6. Opposite angles:
7. Do the diagonals intersect at right angles, or perpendicular?
8. When a diagonal is traced along the parallelogram, does it form two 45-45-90 isosceles triangles?
9. Are all the sides congruent?
10. Are all the angles congruent?
11. Alright! You've completed the parallelogram sorting survey.
