Kinds of quadrilaterals –
see if you can name
them!
p__________
parallelogram
two sets of parallel sides

Other important
polygons you need to
know
PENTAGON

Hint: an
octopus has 8
legs
OCTAGON
Eight sides, eight angles

r _ _ _ _ angles
right angles
look like the letter L and are 90 degrees
Perimeter
Think of Jurassic Park:
“Secure the Perimeter!”
means get the fences
ready!
Perimeter = the measurement
All the way around an object
