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

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

    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.

    ok, so you got that triangles are similar if their angles are the same?

    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.
