Area of Triangles and Parallelograms

The video tutorial explains how to find the area of a parallelogram by transforming it into a rectangle, using the formula base times height. It then demonstrates how to calculate the area of a triangle by forming a parallelogram with two congruent triangles, using the formula base times height divided by 2.

What transformation can be used to find the area of a parallelogram?

• Changing it into a triangle

• Converting it into a square

• Transforming it into a rectangle

• Turning it into a circle

What are the base and height of a parallelogram equivalent to in a rectangle?

• Diagonal and side

• Diameter and radius

• Perimeter and area

• Length and width

How do you calculate the area of a parallelogram?

• Base plus height

• Base times height

• Base divided by height

• Base minus height

If a parallelogram has a base of 14 cm and a height of 10 cm, what is its area?

• 140 cm squared

• 70 cm squared

• 24 cm squared

• 100 cm squared

How can two congruent triangles help in finding the area of a triangle?

• By forming a square

• By forming a parallelogram

• By forming a circle

• By forming a hexagon

What is the first step in finding the area of a triangle using a parallelogram?

• Subtract the base from the height

• Divide the triangle into three parts

• Make an exact copy of the triangle

• Turn the triangle into a circle

What is the formula for the area of a triangle?

• Base minus height

• Base times height divided by 2

• Base plus height divided by 2

• Base times height

What is the area of a triangle with a base of 14 cm and a height of 10 cm?

• 140 cm squared

• 100 cm squared

• 70 cm squared

• 24 cm squared

What is the relationship between the area of a triangle and the area of a parallelogram formed by two congruent triangles?

• The triangle's area is the same

• The triangle's area is triple

• The triangle's area is half

• The triangle's area is double
