text: help! my teacher gave me a grade that doesn't seem right!? here is the exact question from the test:  a on a junior baseball league diamond, the bases are 60 ft. apart.  find the exact distance from second base to home plate.  you cant solve this question with out knowing that the angles the bases make are 90 degrees.  i didn't know this while taking the test, and my teacher wont take the time to look over the question and see if it was kind of unfair.  it was a test on triginometry, not a test on "general knowledge of baseball".    please give my your opinions!  thx, jake   i did all of my reasearch on diamonds.  go to wikipedia and check out their deffinition for diamond/rhombus yes...you are right in that the test requires you to know that a baseball diamond is in fact a square.  but did you write anything on the test that at least shows that you could solve it but for that piece of information...  e.g. let theta be the angle of second base.  so the diagonal = 2 * 60 * cos(theta/2).  then you should get most if not all the credit...if you just whined about not knowing the angles...then i would've given you a 0 on that question.
