Replying to Carpentry teacher tried to injure me

So I was in carpentry this morning. I was cutting an 8x4 sheet of plywood with the saw blade at 45 degrees. About a foot into the cut the plywood got stuck. My teacher, who hates all the students and is the reason half the class dropped the course, told me to raise it up a little bit. He told me to stop when it was the same height of my groin area. After that he started shaking it and it kicked back at me. This didn't seem like an accident because every other time it got stuck he would tell us to turn it off before we pulled it out of the saw.
