Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the formula for the area of a parallelogram?

Back

Area = 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 does 'base' refer to in the context of triangles and parallelograms?

Back

The base is one side of the shape, often the bottom side used to calculate area.

Front

What does 'height' refer to in the context of triangles and parallelograms?

Back

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

Front

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

Back

Height = (Area × 2) / base
