| Question | Answer |
|---|---|
| An angle whose measure is greater than 0 degrees and less than 90 degrees. | Acute |
| An angle whose vertex is the center of a circle and is the same plane as the circle. | Central angle |
| The numeric factor in a term. | Coefficient |
| In a given shape, all angles have the same measure. | Equalangular |
| In a given shape, all sides have the same length. | Equilateral |
| The value of y on the coordinate plane where x=0, called the y-intercept. The value of x on the coordinate plane where y=0, called the x-intercept. | InterceptsOn a circle, an arc that is lar |
| An operation that will undo another operation. | Inverse operations |
| Numbers that cannot be written as a ratio or two integers. The decimal form of the number never terminates and never repeats. | Irrational numbers |
| A triangle with at least two congruent sides. | Isoseles triangle |
| A line drawn in the midst of the points on a scatter plot in an attempt to estimate the mathmatical relationship between the variables used to generate the plot. | Line of best fit |
| On a circle, an arc that is larger than a semicircle and its measure is greater than 180 degrees. | Major arc |
| Numbers that provide information about the cluster and average of a collection of data. | Measures of center |
| The sum of a set of numbers divided by the number of elements in the set. | Mean |
| The number or object that appears most frequently in a set of numbers or objects. | Mode |
| The middle number or item in a set of numbers or objects arranged from least to greatest, or the mean of the two middle numbers when the set has two middle numbers. | Median |
| An arc that is less than a semicircle of 180 degrees. | Minor arc |
| An angle measure greater than 90 degrees and less than 180 degrees. | Obtuse angle |
| The ratio of favorable outcomes to unfavorable outcomes. | Odds of an event |
| Lines in the same plane that do not cross, the distance between the lines in constant. | Parallel lines |
| Lines that intersect at one point forming 90 degrees. | Perpendicular lines |
| A closed figure formed from line segments that neet ony at their endpoints. | Polygon |
| The chance of an event occurring. | Probability |
| Any number that can be writtn in the form a/b, where a and b are integers. | Rational numbers |
| Relating to 90 degrees. | Right |
| A value that will satisfy the equation which has been formed by putting an expression, containing one variable, equal to zero. | Roots of equations |
| A triangle that has no congruent sides. | Scalene triangle |
| An operation that creates an image from an original figure, or preimage. | Transformation |
| A transformation that results in a mirror image of the original shape. | Reflection |
| A transformation about a fixed point such that every point in the object turns through the same angle relative to that fixed point. | Rotation |
| When an image is formed by moving every point on a figure the same distance in the same direction. | Translation |
| This preserves the shape of a figure, but allows the size to change. | Dilation |
| The solutions of a function or the x-intercepts. | Zeros of a function |
