St. Patrick's Day

今天的課程是 review Pythagorean Theorem

我指著PowerPoint上的直角三角形 and try to communicate with my sutdents...



我：c² = a² + b² is the formula for Pythagorean Theorem
　　Sides a and b are called the legs.
　　Who remembers the name for side c?

學生甲：C?

我：...*默默搖頭+點別的學生

學生乙：An...arm?


囧...有腳(legs)不等於就會有手(arm)阿 ||||Orz


我：....Nope, it starts with the letter "H"

學生丙：Head?

我：...囧
