The video tutorial explains how to calculate the area and perimeter of a right triangle. It begins by defining a right triangle and its properties, then demonstrates how to find the area using the formula base times height divided by two. The tutorial also covers labeling the area with square meters. Finally, it explains how to calculate the perimeter by adding the lengths of all sides.

What is a defining feature of a right triangle?

• It has no angles.

• It has a 90-degree angle.

• It has two 45-degree angles.

• It has all sides equal.

Why do we divide the area of a triangle by 2?

• Because a triangle is half of a circle.

• Because a triangle is half of a square or rectangle.

• Because a triangle is half of a hexagon.

• Because a triangle is half of a pentagon.

What is the base of a right triangle typically considered to be?

• The side with the smallest angle.

• The longest side.

• The side opposite the right angle.

• The bottom side on which it rests.

If the base of a right triangle is 10 meters and the height is 8 meters, what is the area?

• 60 square meters

• 20 square meters

• 40 square meters

• 80 square meters

What unit is used to label the area of a triangle?

• Meters

• Meters squared

• Meters cubed

• Meters per second

What is the basic formula for finding the perimeter of a triangle?

• Divide the longest side by the shortest.

• Subtract the smallest side from the largest.

• Add all the sides together.

• Multiply all sides together.

If a right triangle has sides of 10, 8, and 13 meters, what is its perimeter?

• 30 meters

• 32 meters

• 31 meters

• 33 meters

Why is the perimeter not squared?

• Because it is a linear measurement.

• Because it is a volume measurement.

• Because it is a time measurement.

• Because it is a temperature measurement.
