Area of Triangles

Front

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

Back

Area = (base × height) ÷ 2

Front

What do you need to calculate the area of a triangle?

Back

You need the base and the height of the triangle.

Front

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

Back

Area = (10 cm × 5 cm) ÷ 2 = 25 cm²

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 one side of the triangle, often the side on which the triangle stands.

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.

Front

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

Back

The area will also double if the height remains the same.

Front

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

Back

Area = (8 m × 3 m) ÷ 2 = 12 m²

Front

Can a triangle have an area of 0?

Back

Yes, if the height is 0 or if the base is 0, the area will be 0.

Front

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

Back

Area = (6 ft × 4 ft) ÷ 2 = 12 ft²
