prism | a shape created when joining the vertices of two polygons with line segments |
bases | two polygons in the parallel planes |
lateral faces | faces which aren't bases |
lateral edges | segments that form the lateral faces of a polygon |

How do you find the scale factor of similar figures' area? | By squaring the dimensions first. This is not the case is you are already given the scale. Ex: a square divided by b square |
What is the formula to find the scale factor for volume in similar figures? | a cubed divided by b cubed |
How do you find the coordinate of the midpoint on the number line? | If two points have the coordinates x1 and x2 on the number line, the coordinate of the midpoint is the average of x1 and x2 |
How do you find the coordinate of the midpoint given ordered pairs? | The first number in the parenthesis is the average of x1 and x2. The second is the average of y1 and y2. The ordered pair is (first answer, second answer) |
