Question

1. If you know the lengths of two sides of a right triangle, how do you find the third?
2. Could I find the two missing side lengths of a right triangle if I only know one side length and one angle measure?
3. Could I find the two missing angle measures if I know some of the side lengths of a right triangle?
4. What makes a triangle a "special" right triangle? How can special right triangles help me find side lengths?

Answer 1

pythag thrm is a rt tris friend

Answer 2

specials are those that are related to the trig stuff i think; or they are called pythag triples

Answer 3

differently abled triangles?

Answer 4

1. Pythag Theo
2. Trig ra-she-oh
3. Trig ray-she-ohs again
4. 30:60:90/45:45:90

Answer 5

3-4-5

5-12-13

might be the last one

Answer 6

for number one: if the two sides are equal you could calculate the hypotenuse...but can you do the calculation if they are different and you don't know where they are situated?

Answer 7

a^2+b^2 = c^2 can be rewritten to find any missing side

Answer 8

Special right triangles have to my knowledge have always been referred to as "30:60:90" and "45:45:90"

Amistre, I believe she's doing the trig part of geometry.

Answer 9

3:4:5 is a popular right triangle ratio

Answer 10

But it isn't necessarily "special triangles"

Answer 11

trigonometry is the easiest way can you draw this triangle up and i can show how it can be done using trigonometry

Answer 12

makes sense :)

Answer 13

If I know that the side I am given is a and b then I know to add them -- but if the side could be a or b or c then I would need to subtract...If all I know is the measurements and not their orientation...can I still find the third side?

Answer 14

is tis a question given to you, if yes then can you write up the question

Answer 15

yes, kantalope do u mean if they give u ac= 7cm ab=6 bc=?

Answer 16

As for number four: special triangles have set side length patterns in a 45-45-90 triangle the sides adjacent to the 90 are equal. In the 30-60-90 the sides fit the ratio pattern of 3:4:5

Slacker - right if they give me the ac=7 ab=6 what does bc= something
but what if you are just told one side is 6 and one side is 7....is it \[7^{2}+6^{2}=c ^{2} \]
or
solve for b because 7 is the hypotenuse

Answer 17

thing is that formula only get you the hypotenuse you will have to change around a bit to get the other things

Answer 18

I mainly need help with number 4, I don't get it at all

Answer 19

Right so using your 6 and 7 example. If 6 and 7 and the adjacent angles the hyptns is about 9.23 if 7 is the hyptns then the other adjacent side is sqrt of 13...

but for CG -- your "special" triangles are first and equalateral (spelling on that unclear) which has a 90 angle and two 45 degree angles...to add up to 180. To have a triangle like that the two sides adjacent to the 90 have to be equal.
