The Pythagorean Theorem

In mathematics, the Pythagorean theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Geometry

Power of a Point Theorem

The Power of a Point Theorem states that the product of the segments from a point outside a circle to the circle remains constant.

Geometry

Midpoint & Endpoint

The midpoint is the point halfway between two endpoints, while an endpoint is one of the two points that define a line segment.

Geometry

Standard Deviation

Standard deviation measures the spread or dispersion of a set of data points, indicating how much the values deviate from the mean.

Statistic & Probability

Mean & Median & Mode & Range

The mean is the average of data, the median is the middle value, the mode is the most frequent value, and the range is the difference between the highest and lowest values.

Statistic & Probability

Ratio

A ratio compares two quantities, showing how many times one value contains the other, often expressed as a:b or as a fraction.

Algebra

Slope

Slope is basically the amount of slant a line has, and can have a positive, negative, zero or undefined value.
