Section 5.3 or something

Hey class. I did the blog post to get it over with. Anyways, we did some pretty interesting stuff.

For example, how to properly name a shape. Take, for example, this PENTAGON:

This pentagon could be named: ABCDE, AEDCB, and BAEDC. This pentagon could not be named: DACEB.
See the patterns? Self explanatory.

Then, we also learned the simplest definitions of shapes. I'll list them and their definitions here:

Quadrilateral: If and only if (Iff) four sided polygon

Parallelogram: Iff quadrilateral with parallel opposite sides

Rectangle: Iff parallelogram w/ at least 1 right angle

Rhombus (plural rhombi): iff parallelogram w/ at least two consecutive sides

Square: Iff a rectangle and a rhombus.

Kite: Iff quadrilateral w/ 2 pairs disjointed and consecutive sides

Trapezoid: Iff quadrilateral w/ exactly one pair of parallel sides
