Perimeter of an Equilateral Triangle

What is the first step in finding the perimeter of the equilateral triangle?

• Measure the angles of the triangle

• Determine the height of the triangle

• Calculate the area of the triangle

• Find the length of one side

How do you determine the length of the line segment from the center of a circle to the base of the triangle?

• By calculating the area of the circle

• By using the Pythagorean theorem

• By measuring directly with a ruler

• By using the properties of a 30-60-90 triangle

In a 30-60-90 triangle, if the shortest side is x, what is the length of the hypotenuse?

• 2x

• x√3

• 3x

• x

What is the final step to find the perimeter of the equilateral triangle?

• Divide the total length by three

• Add the lengths of all three sides

• Multiply the length of one side by three

• Subtract the radius of the circles from the total length

What is the approximate perimeter of the equilateral triangle?

• 100 units

• 90 units

• 81.96 units

• 60 units
