Saxon Math 8/7 Set 1

base

(1) A designated side (or face) of a geometric figure, or (2) the lower number in an exponential expression.

angle bisector

A line, ray, or line segment that divides an angle into two equal halves.

box-and-whisker plot

A method of displaying data that involves splitting the numbers into four groups of equal size.

alternate exterior angles

A special pair of angles formed when a transversal intersects two lines. Alternate exterior angles lie on opposite sides of the transversal and are outside the two intersected lines.

alternate interior angles

A special pair of angles formed when a transversal intersects two lines. Alternate interior angles lie on opposite sides of the transversal and are inside the two intersected lines.

acute triangle

A triangle whose largest angle measures between 0 degrees and 90 degrees.

chance

A way of expressing the likelihood of an event; the probability of an event expressed as a percent.

acute angle

An angle whose measure is between 0 degrees and 90 degrees.

central angle

An angle whose vertex is the center of a circle.

algorithm

Any process for solving a mathematical problem.

adjacent sides

In a polygon, two sides that intersect to form a vertex.

addend

One of two or more numbers that are added to find a sum.

arc

Part of a circle.

algebraic addition

The combining of positive and negative numbers to form a sum.

absolute value

The distance from the graph of a number to the number 0 on a number line. The symbol for absolute value is a vertical bar on each side of a numeral or variable, e.g., |-x|.

associative property of addition

The grouping of addends does not affect their sum. In symbolic form, a + (b + c) = (a + b) + c. Unlike addition, subtraction is not associative.

associative property of multiplication

The grouping of factors does not affect their product. In symbolic form, a x (b x c) = (a x b) x c. Unlike multiplication, division is not associative.

additive identity

The number 0. See also Identity Property of Addition.

average

The number found when the sum of two or more numbers is divided by the number of addends in the sum; also called mean.

angle

The opening that is formed when two lines, rays, or segments intersect.

altitude

The perpendicular distance from the base of a triangle to the opposite vertex; also called height.

center

The point inside a circle or sphere from which all points on the circle or sphere are equally distant.

area

The size of the inside of a flat shape. Area is measured in square units.

bisect

To divide a segment or angle into two equal halves.

adjacent angles

Two angles that have a common side and a common vertex. The angles lie on opposite sides of their common side.
