Math terms 2

acute angle

• simplify expressions by adding or subtracting like terms
• V=lwh
• an angle whose measure is greater than 0° but less than 90°
• 180°

adjacent angles

• refers to the outside of a circle (keywords: round, circular edge)
• SA=2(lw)+2(lh)+2(wh)
• two angles that share a common vertex and a common side
• property that terms in an expression may be expanded in a particular way to form an equivalent expression

algebraic expression

• All whole numbers (both positive and negative) and zero.
• 180°
• average of data set
• mathematical phrase involving at least one variable and sometimes numbers and operation symbols

circle

• collection of points on the same plane equidistant from the same point
• usually written in parentheses like this: (4,5)
• when two numbers are added/multiplied together, the sum/product is the same regardless of the order
• denominator is "always" 1

circumference of circle

• four sided polygons
• V=lwh
• ratio between two values is always the same, or constant
• refers to the outside of a circle (keywords: round, circular edge)

coefficient

• distance from the center of a circle to a point on the circle
• when two numbers are added/multiplied together, the sum/product is the same regardless of the order
• SA=2(lw)+2(lh)+2(wh)
• number that is multiplied by a variable in an algebraic expression

combine like terms

• simplify expressions by adding or subtracting like terms
• collection of points on the same plane equidistant from the same point
• A percent is a ratio that compares a number to 100.
• All whole numbers (both positive and negative) and zero.

commission

• All whole numbers (both positive and negative) and zero.
• ratio of side lengths in an enlargement to those of the original figure is called the scale factor
• states that the sum of the measures of the interior angles of a triangle is 180°
• amount of money a salesperson earns after selling a product

complementary angles

• sum of their angle measures is equal to 90°
• measure of the likelihood that an event will occur
• in data sets, maximum minus minimum
• when two numbers are added/multiplied together, the sum/product is the same regardless of the order

congruent angles

• result of a single trial of an experiment
• two or more angles that have equal measures
• equation that states that two ratios are equal
• visual display of 5-number summary
