Area and Perimeter of Triangles

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

• P = a + b + c

• P = 2(a + b)

• P = a^2 + b^2 + c^2

• P = 3a

What is the significance of the height in a triangle?

• It is used to calculate the perimeter of the triangle.

• It is crucial for calculating the area and represents the perpendicular distance from the base to the opposite vertex.

• It determines the type of triangle based on its angles.

• It is the longest side of the triangle.

What is the difference between area and perimeter?

• Area measures the space inside a shape, while perimeter measures the distance around the shape.

• Area is the distance around a shape, while perimeter measures the space inside a shape.

• Area and perimeter are the same and can be used interchangeably.

• Area is always larger than perimeter for any given shape.

What is an equilateral triangle?

• A triangle with one angle measuring 90 degrees.

• A triangle where all three sides are of equal length.

• A triangle with two sides of equal length.

• A triangle that has no equal sides.

What is a scalene triangle?

• A triangle with all sides of equal lengths.

• A triangle with at least two sides of equal lengths.

• A triangle with all sides of different lengths.

• A triangle that has one right angle.

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

• Area = base * height

• Area = 1/2 * base * height
