finding the missing side of a trianglei have a triangle it is a right triangle #5 20070501 09:40:36
Re: finding the missing side of a triangleIf you're wellversed in Pythagorean triples, you could also recognise that as double the 51213 triangle, which would help you find the answer quicker. Otherwise, 3daniel's method is perfectly good as well. Why did the vector cross the road? It wanted to be normal. #6 20080207 03:04:34
Re: finding the missing side of a trianglei need help figuring out how to find the missing side of a right triangle with legs: a= 12, and b=9....? #7 20080207 03:36:21
Re: finding the missing side of a triangleIn every rightangled triangle, the sum of the squares of the two shorter sides is equal to the square of the longer side. In other words, to find the length of the longest side, you square the other two sides, add them together, and then square root. ie: #8 20080207 05:06:03
Re: finding the missing side of a triangle
So by following the formula given before: Where: a and b are the sides and c is the hypotenuse. So you have sides a=12 and b=9. Last edited by LuisRodg (20080207 05:07:35) #9 20080401 08:46:47

Re: finding the missing side of a trianglewhat if there is a non right traingle #14 20080525 15:51:29
Re: finding the missing side of a triangle
If a triangle is not a right angled triangle (or simply right triangle), it is not possible to find the length of the third side when two sides are given. However, if the included angle is known, or if all the three angles are known, the length of the third side can be calculated. where a,b, and c are the sides and A, B, and C are the angles. The law of cosines states that Character is who you are when no one is looking. #15 20080526 01:55:58
Re: finding the missing side of a triangleThe cosine law ganesh said is complicated but igloo myrtilles fourmis #16 20081215 09:26:16
Re: finding the missing side of a triangleim so confused okay so i have a triangle with a side of 23 and 9 whats the missing side length #17 20081215 10:30:48
Re: finding the missing side of a triangleWith just that information, you can't tell. The missing side could be anything between 14 and 32. Why did the vector cross the road? It wanted to be normal. #18 20081216 09:42:10
Re: finding the missing side of a triangleis there enyone on right now i really need help like ASAP im completely lost i really dont understand math someone please help ne!!!!!!! #19 20081216 09:47:19
Re: finding the missing side of a trianglePost your question n i will see if i can help. #20 20081218 11:39:36
Re: finding the missing side of a trianglei remember doing this in school but now it doesnt seem to want to work. I have a right triangle and its hypotenuse is 3 and height is 2 how does that not work? #21 20081218 12:33:35
Re: finding the missing side of a triangleokayokayokay sorry i was doing a question where pythagorean theorum doesnt apply apparently because you have to find the area of a triangle and it has a missing side and pythag has nothing to do with it guess theres another way to find the side #22 20081218 12:51:15
Re: finding the missing side of a trianglePythagoras could apply to that, if it's the same triangle as in your first post. Why did the vector cross the road? It wanted to be normal. #23 20081223 03:13:32
Re: finding the missing side of a triangleThis didn't help me...i need to know how to find any side with only one side on a 306090 triangle #24 20081223 04:47:48
Re: finding the missing side of a triangleOn a 306090 triangle, the longest side is always twice as big as the shortest side. Why did the vector cross the road? It wanted to be normal. #25 20081223 04:55:43
Re: finding the missing side of a triangleTo find the any side of a triangle knowing all the angles of said triangle and one side use the law of sines. Say the known side is side "A" and using the angle opposite it as angle A find its sine (i.e. sine(A)). Now set up a proportion:
