High School Geometry – … analytic geometry

Hi there! Welcome to our mathsite!
For the three-year period 2020-2022, we focused on the analytic geometry portion of the Ontario grade 10 math curriculum, with some occasional deviations $\ddots\vdots\ddots\cdots$ .

From 2023 onwards, our focus shifted to proposing problems (e.g. see page 31 here, page 32 here, page 41 here, page 42 here, etc).

Make your visit less hectic and profit from it: CLICK to see quick “tips”:

Search for topics: Look at the “search bar” at the top of this page. Type in a keyword or a few words and see the suggestions that come up. We hope that you can find something useful. However, our aim is to add to, rather than address, what you’ve already known — so you may find us treating familiar things differently. As we add to what you’ve already had, we’ll try to not make things hard.
Stretch your thinking: Leave some time in order to ruminate on what you read, including the “tasks” at the end of (most of) our posts. We really want you to get something, even if it won’t count for marks. Remember: “Doing what doesn’t count for marks might be a mark of those who’ll eventually do what counts”.
Switch to theory: Love abstract, theoretical concepts as much as their concrete, numerical counterparts. If not, most of the material in this blog will become immaterial.

Analytic geometry: straight from factory, sprinkled with poetry, saturated with theory.
