Secondary 4 Math Geometry — Unit Notes
Every definition and theorem this unit expects you to know, stated once each and written to be revised from: 2 definitions and 7 theorems, 5 worked examples, in 6 printable pages. This page lists what the notes cover. The notes themselves come with the Secondary 4 Math bundle.
Unit notes — in the bundle
Not sold separately. The practice worksheet for this unit is free, with no email and no account.
Geometry — what the notes cover
5 sections, in the order the unit is taught. Each entry below is the title of a definition or a theorem the notes state in full.

- Theorem — Minimum conditions for SIMILAR triangles
Also in this section: 1 worked example, 2 notes on method and common errors.
The ratio of similarity and its powers
- Definition — Ratio of similarity
- Theorem — What does to each measure
Also in this section: 1 worked example, 2 notes on method and common errors.
Proportional segments and decomposition
- Theorem — Thales' theorem
Also in this section: 1 worked example, 2 notes on method and common errors.
Angles in a circle
- Theorem — The four measures
- Theorem — Two consequences worth naming

Where the notes are
The notes are one of the documents in the Secondary 4 Math Solutions Bundle, beside the unit test, the challenge problems and every worked answer key. The Geometry practice worksheet is free and stays free.
Every Secondary 4 Math topic — the complete Solutions Bundle
One download, one payment, the whole program. For all 17 Secondary 4 Math units: the worksheet, the reference notes, the challenge set, the unit test and every answer key — these notes included.
- Worked solutions, not answer lists — every step written out
- Covers the whole year's program at this level
- Less than the price of one hour of tutoring — for the entire year's solutions
Practise it, then test yourself
Notes on their own do not make anything stick. This unit has a free, printable practice worksheet, and an end-of-unit test that comes with the bundle.
