What are the applications of right triangles in the real world?

Question

How it is used like in engineering/architecture, etc.
I should be able to make a pop up booklet out of its application, thus it should be very concrete applications.

Answer 1

Look around, like at the corners of your home. They're all over the place.

Answer 2

Soccer goals. I had to make little goals out of PVC pipe for the four and five years olds. Lo and behold, after all these years, I pulled out the old Pythagorean to calculate the hypoteneus. 4'x3'x5' to make the side pieces. This would make a good pop-up (using paper and inches).



Ladders use right triangles - either one, if leaned against a wall, or two right triangles back-to-back, if free-standing.



Right triangles are used as braces for square joints. I'm looking at the deck on my house right now, and it has a post and a cross-bar, braced with a third piece that braces the joint.

Answer 3

In addition to construction (finding the length of the boards needed for roofing, or determining the pitch of the roof and amount of shingles required, for example), right triangles and the associated calculations are used extensively in electrical applications.

To determine the amount of reactive load (and thus the excitation) on a generator, right triangle calculations set the base of a right triangle equal to the "real" power (Megawatts), and the other base (height) of the triangle is the reactive load (Mega volt-amps reactive). The hypotenuse of the triangle is the "apparent" power (Mega volt-amps) which are measurable parameters - voltage and current - that are used to ensure commercial generators are safely operated within the manufacturer's operating limits.

Answer 4

a million+2=3 precise,i'm getting that bit.yet a precise angled triangle conforms to the guideline that the sum squares of the two shortest sides could equivalent the sq. of the longest area.yet 1squared =a million ;2squared=4 and a million + 4=5 yet I make 3 squared =9 and my limited carry close of maths tells me that 5 isn't = 9.Am I the only thats daft?

Answer 5

Little Paper footballs. The Play Button. Support Bars on catwalks and cross beams. The design of the Mayan Pyramids and their layouts, as well as the Athenian Temples layout. I think both of those areas were designed around the right triangle. I'm probably wrong though.

Answer 6

The website below is got lots of well worked out example of how to use the right triangle and the pythagorean theorem.

Answer 7

right triangles are used for house lots, like the property for a house.

not all are squares or rectangles, and theres alot of triangles!

so knowing the lengths and everything could be very helpful so they know how big to build the house, piping, etc...

Answer 8

In the real world, there are tools, and you use the right tools for the job. It is no different with triangles, when you need one, you use the right triangle for the job. It wouldn't work out if you used the wrong tirangle for the job. So, that's how right triangles are needed in the real world.

Answer 9

Right triangles are used in trajectory problems.



Also in surveying.
