Exploring Area Calculations of Parallelograms and Triangles

How can the area of a parallelogram be calculated?

• Half the base times height

• Base times height

• Base minus height

• Base plus height

What geometric transformation is used to turn a rectangle into a parallelogram?

• Reflection

• Translation

• Shifting a side

• Rotation

If a triangle and a parallelogram have the same base and height, how does the area of the triangle compare to the parallelogram?

• The triangle's area is one-fourth

• The triangle's area is double

• The triangle's area is the same

• The triangle's area is half

To find the area of a triangle, you multiply:

• Base plus height

• 1/2 times base times height

• 2 times base times height

• Base times height

Which statement is true about calculating areas?

• A parallelogram's area is calculated differently from a rectangle's.

• A triangle's area is always less than the parallelogram it is derived from.

• A rectangle's area is calculated by adding its base and height.

• A parallelogram can be formed by extending a rectangle's side.
