The perimeter of a triangle is side A plus side B plus side C.
Since we are talking about a right triangle, if you know two sides, then you know the third by the Pythagorean Theorem: A2 + B2 = C2
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.
-- 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.
ask your maths teacher
By adding the three sides.
Add up the sides.
-- Measure or calculate the length of each of its 3 sides. -- Add the lengths of its 3 sides. -- The sum is the perimeter of the triangle.
The perimeter of a triangle is the sum of its three sides.
