 2 A way to directly see that the interior angles of triangle sum to $180^\circ$? 1 Are two numbers, $a$ and $b$, uniquely determined by their addition $a+b$ and product $a b$? 1 How to improve at handling the (mild) complexity of high school trig? 1 How do you revise material that you already half-know, without getting bored and demotivated? 1 A way to directly see the Inscribed angle theorem? (i.e. central angle is twice the inscribed angle)
