Back

A radius is a line segment from the center of the circle to any point on its circumference.

Front

What is a diameter of a circle?

Back

A diameter is a line segment that passes through the center of the circle and has its endpoints on the circle. It is twice the length of the radius.

Front

How do you calculate the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 * base * height.
