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, each with an area that is half of the rectangle's area. 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 plus height

• Base times height

• Base divided by height

• Half the base times the height

How is a rectangle divided to form two triangles?

• By drawing a horizontal line

• By drawing a vertical line

• By drawing a circle inside

• By drawing a diagonal

What is the formula for the area of a triangle derived from a rectangle?

• Half the base times the height

• Base plus height

• Base times height

• Base divided by height

Which of the following is NOT a correct description of the height in a triangle?

• The vertical height

• The slant height

• The perpendicular distance from base to top

• The height along the base

Why is the formula 1/2 base times height applicable to all triangles?

• Because it calculates the area of half a rectangle

• Because it accounts for the entire area of a rectangle

• Because all triangles are similar

• Because it only applies to right triangles
