Is it possible to have an Equilateral Obtuse triangle? (Hint - draw it out to help answer this)
NO! The sides will not all be equal.

What are the three types of angles a triangle can have? BONUS: Draw a triangle for each type (100 pts. each correct triangle)
Right (90 degrees) Obtuse (greater than 90 degrees) Acute (less than 90 degrees)
300
What are the 3 things we look at to classify (name) quadrilaterals?
Pairs of parallel lines, right angles, congruent side lengths
300
Find the volume of figure #3
48 cubic cm

True/False: A trapezoid is a parallelogram
FALSE! (A parallelogram has 2 sets of parallel lines - a trapezoid only has 1 set)

What does a "regular" polygon mean?
All the sides and angles are exactly the same.
400
What are the three names based on the sides? BONUS: share the trick how you remember the difference between them
Equilateral (all sides equal) Isosceles (two sides equal) Scalene (no sides equal)
