Course Overview

The source curriculum is presented as a complete recorded video edition of Get Ready for Geometry . Representative lessons include “Solving a proportion with an unknown variable (example)”, “Pythagorean theorem 2” and “Volume of a cone”. These recordings give concrete examples to revisit while building geometric relationships, diagrams and evidence-based reasoning. Their place in the lesson list is preserved, so you can return to a particular explanation without losing its source position. Introductions, demonstrations, examples, reviews and compilations remain included whenever they appear in the original playlist. Reading a lesson title is useful for locating a topic; working through its reasoning and checking a practice attempt is what makes the recording valuable for learning.

How to study the course

• Videos 1–21: this part of the source list includes “Solving a proportion with an unknown variable (example)” through “Using algebra to find measures of angles formed from transversal”. Label what is given before applying a property. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 22–42: this part of the source list includes “Proof: Sum of measures of angles in a triangle are 180” through “Parallelogram on the coordinate plane”. Separate an observation in a drawing from a justified conclusion. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 43–63: this part of the source list includes “Two-variable linear equations and their graphs” through “Example 3: Factoring quadratics as a perfect square of a sum: (a+b)^2”. Redraw an example with different dimensions or orientation. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 64–84: this part of the source list includes “Factoring perfect squares: missing values” through “Volume of a cone”. Explain the relationship that supports the answer. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.

Who is this for?

This course suits learners studying geometry and teachers looking for recorded explanations of the named geometric topic. It also provides a recorded reference for revisiting a topic after an earlier lesson or study attempt. Choose examples appropriate to your background and allow time to work through the method instead of judging understanding only by how familiar the terminology sounds.

Before you start

Basic arithmetic and the algebra used in the examples are useful. Keep paper, a ruler and a compass when constructions are demonstrated.

Put the lessons into practice

Choose two geometric situations from the lessons and draw your own diagrams. Label the given information, identify the relationship used and write a reason for each step. Change a length, angle or orientation and check which conclusions still follow. For a construction, record the order of operations and explain which geometric property makes it work. Check the final result against the original conditions and distinguish a measured approximation from a conclusion supported by the lesson’s reasoning.

This optional study activity is provided by WikiFree for independent practice. Keep your working notes and use the relevant classroom recording to check a step, definition or interpretation. It is not an instructor-marked assignment.

Certificate / Assessment

Watching the public videos and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. Use your practice output to review what you can explain and repeat independently. The recorded lessons provide study material; completion tracking records your progress through that material.
