Area and Properties of Parallelograms

The video tutorial covers the concepts of bases and heights in parallelograms, focusing on identifying correct height labeling, drawing height segments, and calculating areas. It also discusses the properties of parallelograms and includes exercises on decomposing shapes into triangles to find areas.

Which of the following figures has the height correctly labeled at a 90-degree angle to the base?

• Figure A

• Figure D

• Figure B

• Figure C

What is the relationship between the base and height in a parallelogram?

• The base is always longer than the height.

• The height is always longer than the base.

• The height is perpendicular to the base.

• The base and height are equal.

When drawing the height for a given base in a parallelogram, what is the most important consideration?

• The height should be shorter than the base.

• The height should be longer than the base.

• The height should be at a 90-degree angle to the base.

• The height should be parallel to the base.

How do you calculate the area of a parallelogram?

• Divide the base by the height.

• Subtract the height from the base.

• Add the base and height.

• Multiply the base by the height.

What is the area of a parallelogram with a base of 5 units and a height of 2 units?

• 15 square units

• 12 square units

• 10 square units

• 7 square units

Which statement about parallelograms is true?

• A parallelogram can have one pair of parallel sides.

• Opposite sides of a parallelogram are parallel.

• All sides of a parallelogram have the same length.

• A parallelogram has six sides.

How many pairs of parallel sides does a parallelogram have?

• Four pairs

• One pair

• Three pairs

• Two pairs

What is the area of six triangles if each triangle is 1/18 of a square meter?

• 1/4 square meter

• 1/2 square meter

• 1/3 square meter
