triangle does not have a circumference, a circle has a circumference. A triangle only has a hypotenuse (Pythagoras sort of stuff). The circumference of a circle is the perimeter of it, so, perhaps, if your teacher ask for the circumference of a triangle he/she might mean the perimeter of the triangle.
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
Length of longer leg = 9.4 tan 60 = 16.28 feet Length of hypotenuse = 9.4 ÷ cos 60 = 18.8 feet Perimeter of triangle = 9.4 + 16.28 + 18.8 = 44.48 feet
It depends on what else you know about the triangle.
An SSA triangle is ambiguous.Suppose the triangle is ABC and, with conventional labelling, you know a, b and angle A.Then by the cosine rule, a2 = b2 + c2 - 2bc*Cos(A)This equation will give rise to a quadratic equation in cwhich has 2 solutions. The perimeter is then a + b + c1 or a + b + c2
isosceles,equilateral,rightangled
I quote " The square on the hypotenuse of a rightangled triangle..."
Right Triangle A rightangled triangle, since the last angle has to be 90 degrees
a right angled triangle with the remaining angles both being 45 degrees will be a rightangled triangle and an isosceles triangle.
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
One is 90 degrees, the other two can be any combination that adds up to 90.
ask your maths teacher
By adding the three sides.
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
Add up the sides.
The perimeter of a triangle is the sum of its three sides.
