List 3 ways that we can classify shapes (bonus 4th)
Lines of symmetry/rotational symmetry Amount of sides, vertices, and angles Amount of equal/parallel sides Name of polygon etc.

400
How many lines of symmetry does a circle have?
An infinite amount
400
What is the difference between concave and convex?
Concave is when a shape is curved inward (interior angle greater than 180 degrees) Convex is when a shape is curved outward (all interior angles less than 180 degrees

DAILY DOUBLE!
Bob went to a store and saw a sign that read "Guess the shape of the hidden object based on the clues and win $2!" The clues were: I have a rotational symmetry order 2 I have 4 sides Despite being skilled at math, Bob's guess was incorrect, as the answer turned out to be a rectangle, what was his guess?
500

500
What shape has rotational symmetry order 3?
An EQUILATERAL triangle
