Area of Triangles

Front

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

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is the area of a triangle with a base of 10 cm and a height of 5 cm?

Back

The area is 25 cm² (Area = 1/2 * 10 cm * 5 cm).

Front

If a triangle has an area of 30 cm² and a base of 6 cm, what is the height?

Back

The height is 10 cm (Area = 1/2 * base * height; 30 = 1/2 * 6 * height).

Front

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

Back

Area is measured in square units, such as cm², m², ft², etc.

Front

How do you find the perimeter of a triangle?

Back

The perimeter of a triangle is found by adding the lengths of all three sides.

Front

What is the perimeter of a triangle with sides measuring 5 cm, 7 cm, and 10 cm?

Back

The perimeter is 22 cm (5 cm + 7 cm + 10 cm).

Front

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

Back

The base and height are perpendicular to each other; the area is half the product of these two measurements.

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 area of a triangle with a base of 12 m and a height of 4 m?

Back

The area is 24 m² (Area = 1/2 * 12 m * 4 m).

Front

If a triangle has an area of 40 ft² and a height of 8 ft, what is the base?

Back

The base is 10 ft (Area = 1/2 * base * height; 40 = 1/2 * base * 8).
