2nd 5th 6th Geo Test: Angles, Circles, Surface Area & Volume

Front

What is an angle?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex). It is measured in degrees.

Front

What is the sum of angles in a triangle?

Back

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

Front

What is a circle?

Back

A circle is a shape consisting of all points in a plane that are a fixed distance (radius) from a center point.

Front

What is the formula for the area of a circle?

Back

The area of a circle is calculated using the formula A = πr², where r is the radius.

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is calculated using the formula C = 2πr, where r is the radius.

Front

What is surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

What is the formula for the surface area of a rectangular prism?

Back

The surface area of a rectangular prism is calculated using the formula SA = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

Front

What is volume?

Back

Volume is the amount of space that a substance (solid, liquid, gas) occupies, measured in cubic units.

Front

What is the formula for the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated using the formula V = lwh, where l is length, w is width, and h is height.

Front

What is a right angle?

Back

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