Question

1. If I know the lengths of two sides of a right triangle, how do I 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 (other than the 90 degree angle)?
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?
(Sorry to those who posted on my last question but the site mysteriously deleted it :[ )

Answer 1

1) use Pythagoras theorem p^2+b^2 = h^2
2) yes you can
3) if you know two sides, then you can find missing angle
4) what is 'special' right angle triangle?

FYI: if you know one side .... and any other (angle or side) ... and you can find anything on right angle triangle. just two parameters

Answer 2

Can you elaborate on 2 and 3?

Answer 3

Formulas, Plug-ins (etc).

Answer 4

I told you ... you have three trigonometric ratios

sin(Q) = p/h,
cos(Q) = b/h
tan(Q) = p/b


the other angle would be
(90-Q)

sin(90-Q) = b/h
cos(90-Q) = p/h
tan(90-Q) = b/p

choose your ratio connecting the side and angle you have known, find the missing other ... and move on to other ratio

Answer 5

I know you did, but for some reason the question was deleted and I lost all of my replies :\ thank you for the help
