Front

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

Back

Area = 1/2 × base × height

Front

What do you need to measure to find the area of a triangle?

Back

You need the base and the height.

Front

If the base of a triangle is 8 m and the height is 5 m, what is the area?

Back

Area = 1/2 × 8 m × 5 m = 20 m²

Front

What is the height of a triangle?

Back

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

Front

What is the base of a triangle?

Back

The base is any side of the triangle, often the one at the bottom.

Front

If a triangle has an area of 30 ft² and a base of 10 ft, what is the height?

Back

Height = (Area × 2) / base = (30 ft² × 2) / 10 ft = 6 ft.

Front

What is the area of a triangle with a base of 12 cm and a height of 4 cm?

Back

Area = 1/2 × 12 cm × 4 cm = 24 cm².

Front

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

Back

Square units (e.g., m², cm², ft²).

Front

Can the area of a triangle be negative?

Back

No, area is always a positive value.

Front

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

Back

The area also doubles.
