Calculating Areas of Trapezoids

What shape is a trapezoid?

• A rectangle with equal opposite sides

• A triangle with three equal sides

• A quadrilateral with one pair of parallel sides

• A circle with no sides

What are the parallel sides of a trapezoid called?

• Heights

• Bases

• Diagonals

• Vertices

How is the height of a trapezoid defined?

• The distance between the two bases

• The longest side of the trapezoid

• The diagonal of the trapezoid

• The sum of all sides

What transformation is used to derive the area formula of a trapezoid?

• Folding the trapezoid into a square

• Doubling the trapezoid size

• Cutting and sliding a section to form a triangle

• Rotating the trapezoid

What is the formula to calculate the area of a trapezoid?

• 2 * (Base1 + Base2) * Height

• Base1 * Base2 * Height

• (Base1 + Base2) * Height / 2

• (Base1 + Base2) * Height

Can the area formula for trapezoids be applied to any trapezoid?

• Yes, for all trapezoids

• No, only for isosceles trapezoids

• No, it varies with each trapezoid

• Yes, but only for right-angled trapezoids
