Back

Dependent events are those where the outcome of one event affects the outcome of another. Independent events are those where the outcome of one event does not affect the outcome of another.

Front

What is the formula for the area of a circle?

Back

Area = πr², where r is the radius of the circle.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of two complementary angles is 90 degrees.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

What is the measure of angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

What is the definition of a circle's radius?

Back

The radius is the distance from the center of the circle to any point on its circumference.

Front

What is the relationship between the angles in a linear pair?

Back

Angles in a linear pair are supplementary, meaning their measures add up to 180 degrees.

Front

How do you find the length of a side in a right triangle using trigonometry?

Back

You can use sine, cosine, or tangent ratios depending on the known angles and sides.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2πr, where r is the radius of the circle.
