Area and Perimeter of Triangle

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the perimeter of a triangle?

Back

Perimeter = sum of the lengths of all three sides

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 units²

Front

What is the height of a triangle?

Back

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

Front

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

Back

Base = (Area × 2) / height

Front

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

Back

Area = 1/2 × 8 × 3 = 12 cm²

Front

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

Back

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

Front

If a triangle has sides of lengths 3 cm, 4 cm, and 5 cm, what is its perimeter?

Back

Perimeter = 3 + 4 + 5 = 12 cm

Front

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

Back

Area = 1/2 × 6 × 4 = 12 units²

Front

What is the formula for the perimeter of a triangle?

Back

Perimeter = a + b + c, where a, b, and c are the lengths of the sides.
