Area Of Triangles: The formula to calculate the area of a triangle

The video tutorial explains how to calculate the area of a triangle by first reviewing the area of a rectangle. It demonstrates that by drawing a diagonal in a rectangle, two triangles are formed, and thus the area of one triangle is half the area of the rectangle. The formula for the area of a triangle is derived as 1/2 times the base times the height. This formula is applicable to all triangles, and the video emphasizes the importance of identifying the correct base and height.

What is the formula for calculating the area of a rectangle?

• Base times height

• Half the base times the height

• Base divided by height

• Base plus height

How is the area of a triangle derived from a rectangle?

• By subtracting the height from the base

• By drawing a diagonal to form two triangles

• By dividing the rectangle into four triangles

• By adding the base and height

What is the formula for the area of a triangle?

• Base plus height

• Base times height

• Base divided by height

• Half the base times the height

Which of the following is true about the height of a triangle?

• It is the same as the base

• It is the vertical distance from the base to the top

• It is always the longest side

• It is the diagonal of the triangle

Why is it important to correctly identify the base and height in a triangle?

• To ensure the triangle is equilateral

• To find the perimeter

• To accurately calculate the area

• To determine the type of triangle
