Geometry at home

What is a good homeschool geometry curriculum, with proofs?

One that teaches proof step by step, not only formulas, and covers congruence, similarity, coordinate geometry, right triangle trigonometry, circles and volume. Clareza Academy's Geometry: Structure, Proof, and Measurement is a full-year course with 8 units and 74 skills.

What it covers

Transformations and congruence, triangle congruence and proof, similarity, coordinate geometry, right triangle trigonometry, circles, three-dimensional measurement, and geometric probability.

Proofs, one step at a time

Your teen writes two-column proofs about lines, angles and triangles, plans proofs for new claims, and writes coordinate proofs. Clara, the teacher built into every lesson, works through each proof with them and explains where one went wrong.

Where it sits

It comes after Algebra I and before Algebra II. Physics in Grade 11 expects Algebra I and Geometry first.

What this is not

  • It is not an honors course, and Clareza is not accredited.
  • Clara is an AI and can be wrong about a proof. Read your teen's proofs now and then yourself.
  • There is no live class or human tutor.

Before your child starts: what we collect and why

We collect only what it takes to teach your child: the first name and sign-in you choose, their answers and progress, and their chat with Clara (written by Anthropic's AI, read aloud by OpenAI). Nobody trains AI on it or sells it, and you can see or delete it any time. You create your child's account yourself. Paying by card is how you give consent.

Read what we collect and why

Your consent is needed before we collect anything from your child, and we collect nothing without it. You create your child's account yourself; they never sign up alone.

  • What we collect from your child: the first name and sign-in you choose, their answers, time on lessons and progress, and their chat with Clara. Used to run the lessons, build their transcript and show you how they are doing.
  • Who else handles it: Anthropic (an AI company) receives the chat text and the lesson, with your child's first name but no last name or account details, to write Clara's replies. That is how Clara works, so it is part of the service. If you switch on answering out loud for a child, their voice is turned into text on our own server and then discarded; it is never sent to another company. OpenAI turns lesson text and Clara's replies (which can include your child's first name) into the read-aloud voice. Our email provider sends you reports about your child. Nobody trains AI on your child's data, and nobody sells it.
  • Your rights: see everything collected from your child, have it deleted, or stop further collection at any time, from your account or by emailingour support address. If you refuse the AI sharing above, Clara cannot teach, so the service cannot run. Chats are deleted after 30 days.
  • Safety: if your child writes something suggesting they may be hurt or in danger, we email you and Clareza's owner the same day.

Paying by card is how you give consent. Full details, including how long we keep each thing: Privacy Policy (version 2026-10-05).
