What is Heron's Formula used for?
*
Calculating the area of a triangle given its side lengths
Finding the perimeter of a triangle
Calculating the volume of a pyramid
Determining the height of a triangle
Write down Heron's Formula for the area of a triangle.
*
Given a triangle with sides a = 7 cm, b = 8 cm, and c = 9 cm, calculate the semi-perimeter (s).
*
Given the same triangle (a = 7 cm, b = 8 cm, c = 9 cm), use Heron's Formula to calculate the area. (Round your answer to two decimal places.)
*
Which of the following sets of side lengths can form a triangle suitable for Heron's Formula? (Select all that apply)
*
a = 3 cm, b = 4 cm, c = 5 cm
a = 2 cm, b = 2 cm, c = 5 cm
a = 6 cm, b = 8 cm, c = 10 cm
a = 1 cm, b = 2 cm, c = 3 cm
Match the following triangles with the correct area (rounded to the nearest whole number):
