Here is some vocabulary you might see in your math class!
An angle measuring more than zero degrees and less than 90 degrees
Having the same size and shape
The amount that remains after one number has been subtracted from another
A number that tells how many times the base is multiplied by itself
The inverse of a fraction; when multiplied by the original fraction, it results in a product that equals one
vertex (vertices - plural)
The point of intersection for two sides of a plane figure, three sides of a solid figure, or the endpoints of two rays that form an angle.
A combination of numbers and variables connected by one or more operations signs
Three or more line segments in a plane that forms a closed figure. The line segments never cross but meet at their endpoints.
The result of muliplying two or more numbers
The difference between the least and greatest values in a set of numbers
A triangle with sides of different lengths and no two angles are the same
Surface space that is measured in square units
The distance around a figure
The distance around a circle (the perimeter of a circle)
An angle that measures 180 degrees
An angle measuring more than 90 degrees and less than 180 degrees
Two angles whose sum equals 90 degrees
A line segment that passes through the center of a circle and has its endpoints on the circle
The total of two or more numbers being added
The result of dividing one number by another; the solution to a division problem
The sum of a group of numbers divided by the number of numbers; also known as the average
A value found by ordering a group of data from least to greatest and choosing the middle value of the group.
In a group of values, the value that occurs most often
A solid figure that has triangles for its sides and a polygon as its base
A polygon that has four sides
a quadrilateral with two pairs of congruent, parallel sides
A parallelogram with four right angles
A mirror image of a figure shown over a line of reflection
A drawing of an object that is different in size (usually smaller than the original) but keeps the same proportions
An eight-sided polygon
A polygon with five sides
The ratio of a number to 100 (per one hundred); the symbol %
Figures that have the same shape but different sizes; their sides are proportional, while their corresponding angles are equal
A triangle that has three equal sides and three equal angles
A length that is half the diameter of a circle; the distance from the center of the circle to the circle itself
A triangle with two equal sides and two equal angles
A triangle with one right angle
Two angles whose sum is 180 degrees
order of operations
Rules that tell which steps to follow when solving an expression. PEMDAS
A parallelogram with all sides equal and congruent. Looks like a diamond or a square that fell over.
A number that when multiplied by itself results in the given number.
An equation stating that two ratios are equal
To make a fraction easier to work with by taking out common factors
The horizontal number line of a coordinate graph
The vertical number line of a coordinate graph
The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair.
The value on the y-axis used to locate a point on the coordinate graph. It is the second value in an ordered pair.
Two numbers listed in a specific order; it describes a point on the coordinate graph
