The original video can be viewed here. For many high school students returning to class this month, it may seem like geometry and trigonometry were created by the Greeks as a form of torture.
The three sides of a right-angled triangle have specific names. The hypotenuse (\(h\)) is the longest side. It is opposite the right angle. The opposite side (\(o\)) is opposite the angle in ...
