The video tutorial explains how to calculate the area of any triangle by first understanding the area of a rectangle. It demonstrates that a triangle's area is half of a rectangle's area, using the formula area = 1/2 * base * height. The tutorial covers how to identify the base and height in different types of triangles, such as acute, obtuse, and right triangles. It provides examples and practice problems to reinforce the concept, emphasizing the importance of using square units for area measurement.

What are the new terms used for a triangle's dimensions instead of length and width?

• Radius and diameter

• Base and height

• Edge and angle

• Perimeter and area

How is the height of a triangle defined?

• The sum of all sides divided by 2

• The longest side of the triangle

• The side opposite the right angle

• The distance from the base to the opposite vertex

Why is the height of a triangle sometimes drawn outside of it?

• In case of obtuse triangles

• Only in right triangles

• For acute triangles

• Never drawn outside

What is the correct formula for calculating the area of any triangle?

• Area = 2(base + height)

• Area = 1/2 base x height

• Area = base x height

• Area = base + height
