Understanding the Area of Triangles and Parallelograms

What strategy did Diego use to find the area of the triangle?

• He used a ruler to measure the sides directly.

• He calculated the perimeter first.

• He used a protractor to measure angles.

• He decomposed the triangle into a trapezoid and a smaller triangle.

How did Jada form a parallelogram with her triangle?

• By rotating a copy of the triangle and aligning it with the original.

• By cutting the triangle into smaller pieces.

• By folding the triangle in half.

• By drawing a line through the triangle's center.

What is the formula used to calculate the area of a parallelogram?

• Base minus height

• Base divided by height

• Base plus height

• Base times height

When converting a triangle into a parallelogram, what must be true about the base and height?

• They must be perpendicular to each other.

• They must be parallel.

• They must form a right angle.

• They must be equal.

What is the first step in forming a parallelogram from a triangle?

• Measure the angles of the triangle.

• Draw a line parallel to one side of the triangle.

• Copy the triangle and rotate it.

• Calculate the perimeter of the triangle.

Which of the following triangles has the greatest area?

• Triangle A

• Triangle C

• All have the same area

• Triangle B

How can you verify that two lines are parallel when forming a parallelogram?

• Ensure they never intersect.

• Check if they form a right angle.

• Measure the distance between them at multiple points.

• Check if they are the same length.
