Area of a Triangle

Front

What is the formula for calculating the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

What do you need to know to find the area of a triangle?

Back

To find the area of a triangle, you need to know the base and the height.

Front

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

Back

The area is (10 cm × 5 cm) / 2 = 25 square cm.

Front

What is the height of a triangle?

Back

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

Front

What units are used to measure the area of a triangle?

Back

Area is measured in square units, such as square centimeters (cm²), square meters (m²), etc.

Front

If a triangle has an area of 30 square units and a base of 6 units, what is the height?

Back

Using the formula Area = (base × height) / 2, the height is (30 × 2) / 6 = 10 units.

Front

What is the area of a triangle with a base of 8 m and a height of 4 m?

Back

The area is (8 m × 4 m) / 2 = 16 square meters.

Front

Can the area of a triangle be negative?

Back

No, the area of a triangle cannot be negative; it is always a non-negative value.

Front

What is the relationship between the base and height in calculating the area of a triangle?

Back

The area of a triangle is directly proportional to both the base and the height.

Front

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

Back

Increasing the height of a triangle while keeping the base constant will increase the area.
