What is perimeter?
Perimeter is the outer boundary of a shape.
What is area?
A measurement of the amount of space inside a 2-D object.
True or False:
Volume is a measurement of the amount of space a 3-D object takes up and therefore is measured in units3. ex. cm3 or m3

What are the 3 main steps to finding an angle?
1. Line up the center point of the protractor with the vertex (or point where the lines meet)
2. Rotate it so then the 0* falls along one of the lines
3. Trace the protractor towards the second line, recording the number that it falls on - and that is your angle
