What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What are complementary angles?

Back

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

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

In a quadrilateral, if two angles are equal and the third angle is equal to their sum, what can be said about the fourth angle?

Back

The fourth angle is twice the sum of the other three angles.

Front

What is the formula for the circumference of a circle?

Back

The circumference (C) of a circle is given by the formula C = 2πr, where r is the radius.

Front

How do you find the radius of a circle if the circumference is known?

Back

To find the radius, use the formula r = C / (2π), where C is the circumference.

Front

What is the formula for the area of a rectangle?

Back

The area (A) of a rectangle is given by the formula A = length × width.

Front

If the length of a rectangle is 15 inches and the width is 9 inches, what is the area?

Back

The area is 135 in² (15 × 9 = 135).

Front
