how do u get the perrimeter of a triangle?

Question

it has a right angle.. and i really don't know how!!! please tell me!!

Answer 1

for the perimiter you add the 3 sides together.
if you are trying to find one side use pythagoreoum's therom which is:
a is side 1
b is side 2
c is side 3 (hypotonuse) (longest side)
a squared + b squared = c squared
OR if you are finding the area the formula is:
A=1/2bh
hope i helped!

Answer 2

You can always find the perimeter of ANY polygon by adding the lengths of all of the sides. If there is a missing side of a right triangle, you can use Pythagorean Theorum (a^2 + b^2 = c^2) there c is the hypotenuse.

Area of a triangle is 1/2*base* height

Hope this helps.

Answer 3

Well, in any triangle, you would have to add all of the sides. If you have a right angle, if you only have some of the sides, you can always use the pythagorean theorem or the basic cosine, sin and tangent to get the last side.

Answer 4

Perimeter of ANY triangle is the sum of the 3 sides. If you have the sides, add them together.

Answer 5

You might have heard of Pythagoras' Theorem. It states that A^2+B^=C^2. C will always be your hypotenuse(Diagonal line) and A and B will always be the 2 legs. Fill in the information given and it should become a simple math problem.

Answer 6

Remember: The perimeter of ANY shape, no matter how many sides is just the sum of all the sides.

Answer 7

hypotenuse+leg+leg=PERIMETER
