Identify the characteristics of a triangle.

• A triangle has four sides and four angles.

• A triangle can have any number of sides depending on its type.

• The sum of a triangle's interior angles is 360 degrees.

• A triangle has three sides, three angles, and the sum of its interior angles is 180 degrees.

What is the formula for calculating the area of a rectangle?

• Area = length × width

• Area = length ÷ width

• Area = 2 × (length + width)

• Area = length + width

How do you calculate the area of a circle?

• A = πd

• A = r² + h²

• A = 2πr

• A = πr²

What is the formula for the area of a triangle?

• Area = 2 * base * height

• Area = 1/2 * base * height

• Area = base + height

• Area = base * height

Describe the properties of a square.

• A square has curved edges and varying angles.

• A square has three equal sides and one obtuse angle.

• A square has four equal sides, four right angles, equal diagonals, and symmetrical properties.

• A square has four unequal sides and no right angles.

What is the formula for calculating the volume of a cube?

• V = 6s, where V is the volume and s is the length of a side.

• V = s^3, where V is the volume and s is the length of a side.

• V = s^2, where V is the volume and s is the length of a side.

• V = 2s^3, where V is the volume and s is the length of a side.
