Circle Theorems for High School Geometry: 1 page visual interactive "doodle notes" set -


When students color or doodle in math class, it activates both hemispheres of the brain at the same time. There are proven benefits of this cross-lateral brain activity:

- new learning

- relaxation (less math anxiety)

- visual connections

- better memory & retention of the content!


Students fill in the sheets, answer the questions, and color, doodle or embellish. Then, they can use it as a study guide later on. Graphic doodle and sketch notes take full advantage of Dual Coding Theory (the way brains process visual and linguistic information) to maximize retention.


Content includes:

- Inscribed angles that intercept the same arc (or congruent arcs) are congruent.

- An angle inscribed in a semi-circle is a right angle.

- The measure of a central angle is twice the measure of the inscribed angle that intercepts the same arc.

- Opposite angles of an inscribed quadrilateral are supplementary.

- A radius (or diameter) that is perpendicular to a chord bisects the chord.

- Radii of the same circle are congruent.

- Arcs that intercept congruent chords are congruent.

- Chords that are congruent are equidistant from the center.

- The segments from two tangent points to the point that the tangents meet outside the circle are congruent.

- A radius drawn to a tangent is perpendicular to the tangent.

Visual note taking strategies like sketch notes or doodle notes are based on dual coding theory.  When we can blend the text input with graphic/visual input, the student brain processes the information differently and can more easily convert the new learning into long-term memory.


This strategy also integrates the left and right hemispheres of the brain to increase focus, learning, and retention!

1 page is included, plus an answer key, sample, and info.


Reviews from other teachers:

-Used as a study guide for my daughter in Geometry! She is filling in the notes as a way to review the topics taught throughout the year!

-It was great to use in a presentation visual. Thanks for all of the doodle notes! I did use it with a few kids individually as a scaffold

-I love using this resource for when I work through circles. Having those color notes and visual really make the learning more interactive for the students

-I love the doodle notes! Some of my students love them, some just tolerate them. I view it as differentiating! Thanks for the great resource!

-Doodle notes work well with my sped students.
