What is the formula to calculate the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the base of a triangle?

Back

The base is one side of the triangle, often the side on which the triangle stands.

Front

What is the height of a triangle?

Back

The height is the perpendicular distance from the base to the opposite vertex.

Front

If the base of a triangle is 10 m and the height is 5 m, what is the area?

Back

Area = 1/2 × 10 m × 5 m = 25 m²

Front

What units are used to measure the area of a triangle?

Back

Square units (e.g., m², cm², ft²) are used to measure area.

Front

What happens to the area of a triangle if the height is doubled?

Back

The area of the triangle also doubles.

Front

What is the relationship between the base and height in calculating the area of a triangle?

Back

The area is directly proportional to both the base and height.

Front

Can a triangle have an area of zero?

Back

Yes, if the height is zero or if the base and height are not perpendicular.

Front

What is a right triangle?

Back

A right triangle has one angle that measures 90 degrees.

Front

How do you find the height of a triangle if you know the area and base?

Back

Height = (Area × 2) / base.
