It depends on what information about the other sides and angles you do have.


How do you find the perimeter of a right triangle when the length of one side is unknown?

You begin by finding the length of the unknown side. The square of the hypotenuse is equal to the sum of the squares of the two legs. Then once you have the lengths of all 3 sides, you adum all up, and you have the perimeter.


How can pythagoream theorem be used to find a missing side length of a right triangle?

It can be found by: hypotenuse squared minus known side squared = unknown side squared


How can you often determine unknown side lengths of a composite figure?

you can see the length of base1(example) and see the length of base2 to find out the answer of lets say the top base of a trapezoid.


The length of the longest side of a right triangle is 3 more than the length of the shorter side the length of the hypotenuse is 3 more than the length of the longer side find the length of each side?

Let's call the unknown length x and use Pythagoras' theorem: x2+(x+3)2 = (x+6)2 By substituting 9 for x you'll find that only 9 will satisfy the above conditions. Shorter side = 9 units Longer side = 12 units Hypotenuse = 15 units

How do you find the width of a rectangle when you only given the length and perimeter?

if you have the length of one side - plus the perimeter... Divide the perimeter by 2, then subtract the known side - this leaves you with the unknown dimension. For example... Say you have a side length of 10, and a perimeter of 30. 30/2 = 15, subtract 10 from that - and you get the missing measurement of 5.
