Area of Triangles (Geo)

Front

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

Back

Area = 1/2 × base × height

Front

What is the base of a triangle?

Back

The base is one side of the triangle, often the bottom side, used in calculating the area.

Front

What is the height of a triangle?

Back

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

Front

If a triangle has a base of 10 units and a height of 5 units, what is its area?

Back

Area = 1/2 × 10 × 5 = 25 square units.

Front

What is the area of a triangle with a base of 12 ft and a height of 8 ft?

Back

Area = 1/2 × 12 × 8 = 48 ft².

Front

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

Back

Height = (Area × 2) / base.

Front

What is the area of a triangle with a base of 24 ft and a height of 10 ft?

Back

Area = 1/2 × 24 × 10 = 120 ft².

Front

What is the area of a triangle with a base of 15 units and a height of 6 units?

Back

Area = 1/2 × 15 × 6 = 45 square units.

Front

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

Back

The area of the triangle also doubles.

Front

What is the area of a triangle with a base of 20 units and a height of 3 units?

Back

Area = 1/2 × 20 × 3 = 30 square units.
