Area of Triangles

Front

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

Back

Area = 1/2 × base × height

Front

What is the area of a triangle with a base of 10 units and a height of 6 units?

Back

Area = 1/2 × 10 × 6 = 30 units²

Front

If the base of a triangle is doubled, what happens to the area?

Back

The area also doubles.

Front

What is the height of a triangle if the area is 20 units² and the base is 5 units?

Back

Height = (Area × 2) / base = (20 × 2) / 5 = 8 units

Front

What is the perimeter of a triangle with sides measuring 5 units, 12 units, and 13 units?

Back

Perimeter = 5 + 12 + 13 = 30 units

Front

What is the area of a triangle with a base of 14 units and a height of 5 units?

Back

Area = 1/2 × 14 × 5 = 35 units²

Front

If a triangle has an area of 50 units² and a height of 10 units, what is the base?

Back

Base = (Area × 2) / height = (50 × 2) / 10 = 10 units

Front

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

Back

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

Front

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

Back

Area = 1/2 × 8 × 3 = 12 units²

Front

What is the area of a triangle with a base of 12 units and a height of 10 units?

Back

Area = 1/2 × 12 × 10 = 60 units²
