Area of Triangles

Front

What is the formula for 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, typically the one on the bottom when the triangle is drawn.

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 in and a height of 4 in?

Back

12 in²

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

Back

30 ft²

Front

How does changing the height of a triangle affect its area?

Back

Increasing the height increases the area, while decreasing the height decreases the area, assuming the base remains constant.

Front

What happens to the area of a triangle if both the base and height are doubled?

Back

The area becomes four times larger.
