  • Okay, just after hitting the "Post" button, I re-read and realized I made a mistake toward the end of what I said. You DID SAY it wrong on the second triangle but the "legs" (non-hypotenuse sides) of a 45-45-90 triangle ARE the same size. So your two 1's ARE the same length (even though they weren't quite drawn that way).

    I was running out of characters, but what I meant at the end was what you said at :52-:53. Before putting any teaching video on, you should make sure it is done correctly.

  • YOU HAVE, BEYOND THE SHADOW OF A DOUBT, GOT TO BE ABSOLUTELY, POSITIVELY, KIDDING ME! Do you not even "proof-read" your own videos????? The side opposite the 30-degree angle is NOT the smallest side. It is the second smallest (and second largest) side. YOU NEED TO SWITCH THE '1' & 'ROOT 3'. And what the hell r u saying at 1:05-1:08? And then, HOLY CRAP, you totally screwed up the 2nd triangle-with what you said AND wrote. Your two 1's aren't even the same length! And, "like this way"??? GARBAGE!
