it depends on the triangle.if it is a "pure" triangle (symetrical on all sides) then the permeter is 9
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
Measure it or use trigonometry if the 'included' angle is given.
Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
Some times you do. If you know all of the side lengths, then you can just add them to find the perimeter, if one of the sides is the same as the height, then you may need to find it.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
You cannot since there is insufficient information.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, as all three sides of an equilateral triangle are equal in length. Therefore, if the length of one side of the equilateral triangle is represented by "s," the perimeter would be 3s. This is because there are three sides in total that need to be added together to find the perimeter of the equilateral triangle.
the perimeter is 36 and the area is 144
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
An equilateral triangle has three sides of exactly the same length. Therefore, if one side of the triangle is equal to 12 yards, then the perimeter of the triangle is equal to 12 x 3 = 36 yards.
subtract the two sides that you know from the perimeter to get the unknown side.
