|
| A | B |
|---|
| Perimeter | Distance around a figure |
| Perimeter formula | P = sum of all sides |
| Area | space contained in a figure, expressed in square units |
| Area formula for a triangle | A = 1/2 * b * h |
| Area formula for a parallelogram | A = b * h |
| Area formula for a trapezoid | A = 1/2 * (b1 + b2) * h |
| Circumference | Distance around a circle |
| Circle | Set of all points in a plance that are the same distance from a point called the center |
| Radius | Distance from the center to any point on the circle |
| Diameter | Distance across the circle through its center |
| Pi | Ratio of any circle's circumference to its diameter |
| Circumference formulua | C = Pi * d |
| Circle area formula | A = pi * r * r |
| Perpendicular | Forms a right angle |
