Make geometric constructions Videos 3 videos
No hard hat needed here–we're talking about mathematical constructions. If you're using a straight edge, a compass, and a pencil, you're working...

Prove geometric theorems Videos 4 videos
Formal proofs present the oh-so-mathematical evidence in two columns: one for the statement they are claiming is true, and the other for the reason...
Indirect proofs (or proofs by contradiction) prove their conclusion by showing that the opposite cannot be true. You can use this in math and in ar...
If you already know what a conditional statement is, then you're smarter than you look. And boy do you look smart.
