What is a coterminal angle?

Back

Coterminal angles are angles that share the same terminal side when drawn in standard position. They can be found by adding or subtracting multiples of 360°.

Front

How do you calculate the mean of a set of numbers?

Back

To calculate the mean, sum all the numbers and divide by the count of numbers. Mean = (Sum of numbers) / (Count of numbers).

Front

What is a reference angle?

Back

A reference angle is the acute angle formed by the terminal side of an angle and the x-axis. It is always positive and less than or equal to 90°.

How do you find the median of a set of numbers?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there is an even count, average the two middle numbers.
