angle whose measure is equal to 90 degrees

an angle whose measure is greater than 0 degrees but less than 90 degrees

mathematical sentence that is created by placing an equals sign, = , between two expressions

-40/8

in data sets, maximum minus minimum (high-low)

angle whose measure is equal to 180 degrees

1/5 + 2/5

a mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥

average of data set

πr²

denominator is "always" 1 with

SA=FB, TB, SS or TB, FB, LR or circle method

sum of their angle measures is equal to 90 degrees

a letter or symbol that is used to represent a quantity

angle whose measure is greater than 90 degrees

equal to twice the radius of the circle

operations that undo each other

ratio of the circumference of a circle to its diameter

two angles that share a common vertex and a common side

order numbers least to greatest then find the middle value (if 2 middle values, find average of both)

equation that states that two ratios are equal

ratio between two values is always the same, or constant

distance from the center of a circle to a point on the circle

refers to the outside of a circle (keywords: round, circular edge)

- 3x < 24

amount added to the cost price of goods to cover overhead and profit

states that the sum of the measures of the interior angles of a triangle is 180 degrees

v=lwh

two ratios have the same value when simplified

deduction from the usual cost of something
