Circle theorems - MATCH UP
These match up cards are for the first few common circle theorems (angle at centre, angle in semicircle and angles in same segment). I introduce circle theorems using nrich's dotted circles as it really emphasises the isosceles triangles. Then I give students this match up. The aim is for students to match up the question to the answer and then the reasons. The reasons are the hardest as there are often many different ways to answer a question. Last time I used it I deleted many of the reasons and got the students to write them down which made it easier and enabled them to practise the necessary skills. Great for a poster and I do love this activity. I once had two non-mathematicians who were observing really going for the match up and getting all the answers right! Please comment if you use it and any suggestions welcome!
