Area of triangles

Front

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

Back

Area = 1/2 × base × height

Front

If a triangle has a base of 10 cm and a height of 5 cm, what is its area?

Back

25 cm²

Front

What is the area of a triangle with a base of 8 m and a height of 3 m?

Back

12 m²

Front

Define 'base' in the context of a triangle.

Back

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

Front

Define 'height' in the context of a triangle.

Back

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

Front

What is the area of a triangle with a base of 6 mm and a height of 4 mm?

Back

12 mm²

Front

If the area of a triangle is 30 cm² and the base is 10 cm, what is the height?

Back

Height = 6 cm (Area = 1/2 × base × height => 30 = 1/2 × 10 × height).

Front

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

Back

The area doubles.

Front

What is the area of a triangle with a base of 12 units and a height of 5 units?

Back

30 units²

Front

If a triangle has an area of 24 cm² and a base of 8 cm, what is the height?

Back

Height = 6 cm (Area = 1/2 × base × height => 24 = 1/2 × 8 × height).
