I'm especially interested in multi-step questions - or puzzles - that encourage students to select a series of techniques to arrive at a solution. The hope is that students will develop the resilience needed to answer, for example, harder geometry questions. My particular focus is Circle Theorems, which I also use for one of my SSDD resources as the 'surface' with the 'different deep' being other shape topics such as Pythagoras, Trigonometry, and arc length & segment of a circle.

Recap activity #5 with the Circle Theorems on one page.

** Updated May 2019 to include answers in the PowerPoint file **

(Prompted by original pile-up ideas from others on Pythagoras, Trigonometry - and Circle Theorems.)

This puzzle is the fifth in a series of consolidation exercises/angle chases on the topic of Circle Theorems.

All of the Circle Theorems are present with “two radii and a chord make an isosceles triangle” and “a radius that is perpendicular to a chord divides the chord into two equal parts” in there too.
