Keyboardmonkey's Little Shop of Circle Theorems Puzzles

Average Rating4.86
(based on 117 reviews)

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.

Circle Theorems Revision Exercise #14

(8)
Recap activity #14 with the Circle Theorems on one page. ** Answers included in the PowerPoint file ** (Prompted by original pile-up ideas from others on Pythagoras, Trigonometry - and Circle Theorems.) This puzzle is the fourteenth 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. See Speaker Notes should you wish to customise the PowerPoint slide. (Edited March 2020, mainly for reasons of presentation. Answers remain unchanged. ) [Mr Barton Maths Resource of the Week hyperlink removed February 2024 following request from TES Admin]
