Just imagine that this is a right triangle where d is the altitude. Find the values of a, b, c, d. About the Right Triangle Similarity.... |\ Given: a+b = 18 | \ a | \ | /\ 6| / \ | /d \ b | / \ | / \ |/_________\ c Please help me... Thanks

First, you know how to figure out c right? Just use the Pythagorean theorem: a^2+b^2=c^2 6^2+b^2=18^2 b^2=288 b=16.97 (approximately)

Okay, that's good too XD do you understand the Pythagorean theorem now? If not, look at this: http://www.mathsisfun.com/pythagoras.html

@14yamaka where did you get a^2+b^2=c^2 from?!!

...? are you pulling my leg hoblos?? :P or for real?

are you following Jenuine? XD

yeah, i got the pythagorean theoren but i still dont know how to find the other variables

Ok, so now the proof of triangular similarity we have to know that before going on

Do you know what makes two triangles similar?
anonymous
  • anonymous
no
anonymous
  • anonymous
If the angles in two triangles are the same, they are similar.

It is generally frowned upon to repost the same question when it has already been answered once. If you delete this post and go back to the first one, I will help you.

oh....make sure you don't do this again okay? X( I know you meant no harm, but it can cause bad feelings so...
anonymous
  • anonymous
sure.. ok

  • anonymous
ok, so you got that triangles are similar if their angles are the same?
anonymous
  • anonymous
yes
anonymous
  • anonymous
Proof for triangle similarity: angle XYZ and angle YWZ are both right angles angle Z is shared so both triangles have this angle. If two of the angles are the same, the remaining angle is also the same. Since all three of the angles are the same, the triangles are similar.
