What is a supplementary angle?

Back

A supplementary angle is an angle that, when added to a given angle, results in a sum of 180 degrees.

Front

How do you find the supplement of an angle?

Back

To find the supplement of an angle, subtract the angle from 180 degrees.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What are the coordinates of a point after a 90-degree clockwise rotation?

Back

To rotate a point (x, y) 90 degrees clockwise, the new coordinates will be (y, -x).

Front

What is the formula for finding the missing angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. To find a missing angle, subtract the sum of the known angles from 180 degrees.

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

How do you solve for x in an equation?

Back

To solve for x, isolate x on one side of the equation using algebraic operations such as addition, subtraction, multiplication, or division.

Front

What is the value of x if the equation is x + 10 = 75?

Back

To find x, subtract 10 from both sides: x = 75 - 10, so x = 65.

Front

What is the definition of an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

Front

What is the sum of the interior angles of a polygon with n sides?

Back

The sum of the interior angles of a polygon with n sides is (n - 2) * 180 degrees.
