What is the formula? | Formula |
Area of a triangle is... | A = 1/2 the base times the height |
The measurement of a right angle is ... | 90 degrees |
The measurement of an acute angle is ... | greater than zero and less than 90 degrees |
The measurement of an obtuse angle is ... | greater than 90 degrees and less than 180 degrees |
The Area of a rectangle | A = lw |
The Perimeter of a rectangle | P = 2l + 2w |
The Area of a square | one side squared |
The Perimeter of a square | 4s |
The Pythagorean Theorem | the sum of the sides squared equals the hypotenuse squared |
The Area of a parallelogram ... | A = bh |
The Perimeter of a parallelogram ... | P = 2l + 2w |
The Area of a circle | Pi times radius squared ( make sure to square the radius first, then multiply that times Pi) |
The Circumference of a circle | C = 2 times Pi times r or Pi times diameter |
The Volume of a Sphere | V = (4/3) times Pi times radius cubed (make sure to cube the radius first) |
The Volume of a cylinder | Pi times radius squared times height (make sure to square the radius first) |
The Volume of a rectangular prism or solid | V = lwh |
The Surface Area of a rectangular prism or rectangular solid | SA = 2lw + 2wh + 2lh |
How do we get the measure of each interior angle of a regular polygon (n = number of sides) | ( (n-2)/n ) times 180 |
Slope intercept form of a linear equation | y = mx + b |
The formula for finding slope | m = (y sub 2 - y sub 1) divided by (x sub x divided by x sub 1) or the change in y divided by the change in x |
