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 units and a height of 5 units, what is its area?

Back

Front

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

Back

12 cm²

Front

Define the term '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

What is the area of a triangle with a base of 7 m and a height of 4 m?

Back

14 m²

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 is the area of a triangle with a base of 12 mm and a height of 10 mm?

Back

60 mm²

Front

If the area of a triangle is 30 units² and the base is 10 units, what is the height?

Back

Height = 6 units (Area = 1/2 * base * height => height = 2 * Area / base).

Front

What is the area of a triangle with a base of 5 inches and a height of 2 inches?

Back

5 inches²
