Understanding the Area of a Right Triangle

What is a defining characteristic of a right triangle?

• It has two equal sides.

• It has one angle measuring 90 degrees.

• It has all angles less than 90 degrees.

• It has three equal angles.

Which formula is used to calculate the area of a right triangle?

• Area = base + height

• Area = (base * height) / 2

• Area = base * height

• Area = base / height

How is the area formula for a right triangle derived?

• By doubling the triangle to form a rectangle.

• By using the Pythagorean theorem.

• By measuring the perimeter.

• By comparing it to a circle.

If a right triangle has a base of 8 cm and a height of 5 cm, what is its area?

• 40 cm²

• 10 cm²

• 20 cm²

• 30 cm²

Why is it important to include square units when stating the area?

• To show the measurement is in three dimensions.

• To differentiate from perimeter.

• To indicate the measurement is in two dimensions.

• To specify the type of triangle.
