sector is proportional to the size of the interior angle.
SIMILAR TRIANGLES triangles that have identical angle measurements and proportionate
sides SLOPE the ratio between the vertical rise and the horizontal run of a line slope =
SOLUTION a known value or set of values
Example: In the equation x + 5 = 15, the solution is x = 10. Some equations have
more than one solution.SQUARE Squares are special rectangles; therefore, any fact about rectangles also applies to
squares. Squares have the following properties:
- All four sides are equal.
- area = (side)^2 = s^2
- perimeter = 4(side) = 4s
- The diagonals are perpendicular.
STANDARD DEVIATION A measure used to quantify how much the data in a set deviates from
the standard (mean). A low standard deviation means that the numbers are close together,
while a high standard deviation means that the numbers are spread out over a large range.
