Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

How do you find the value of x in a rectangle when given the perimeter?

Back

Use the formula for perimeter: P = 2(length + width). Solve for x.

Front

If the side lengths of two cubes are in the ratio 2:3, what is the ratio of their volumes?

Back

The ratio of their volumes is 8:27.

Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and vertex.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie on opposite sides of a transversal and inside the two lines.

Front

Calculate the area of a triangle with a base of 6 in and a height of 4 in.

Back

Area = 1/2 * 6 * 4 = 12 in².

Front

If a rectangle has a length of 5 cm and a width of 3 cm, what is its perimeter?

Back

Perimeter = 2(length + width) = 2(5 + 3) = 16 cm.

Front

What is the relationship between the sides of a cube and its volume?

Back

Volume = side³; if the side length doubles, the volume increases by a factor of 8.

Front

Identify two angles that are adjacent to each other in a diagram.

Back

Adjacent angles share a common vertex and side.

Front

What is the sum of the interior angles of a triangle?

Back

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