If your secondary students feel like circle theorem is like putting a square peg in a round hole, help them see the point of all these angles by using a triangular one instead Enrich your RE lessons with social science data. Author: Andy Lutwyche. These sheets contain sketches of circle theorems and blanks for the students to fill in in their own words. The idea was to save them drawing poor sketches in their books and to write the rules in their own words. Download this resource here.

The expectation is that: All students will develop confidence and competence with the content identified by standard type All students will be assessed on the content identified by the standard and the underlined type; more highly attaining students will develop confidence and competence with all of this content Only the more highly attaining students will be assessed on the content identified by bold type. The highest attaining students will develop confidence and competence with the bold content. Open link. A fantastic, student friendly powerpoint which provides clear proofs for six circle theorems. You will need to register for a TES account to access this resource, this is free of charge. Eight circle theorems are demonstrated through a PDF handout and dynamic Geogebra files along with proofs of each result. The pack contains 18 flash cards which should be printed back to back so that the question is on one side and the answer is on the other.

A tangent is a line that just skims the surface of a circle. It hits the circle at one point only. A tangent line of a circle will always be perpendicular to the radius of that circle.

In my opinion, the most important shape in maths is the circle. Once we draw some lines inside a circle, we can deduce patterns and theorems that are useful both theoretically and in a practical sense. The defining feature of the circle is its constant radius, and I hope to show you that starting from this simple line, we can derive all the circle theorems you need to understand. Firstly, we have to know how to construct an isosceles triangle from two radii. Since every radius is the same, drawing two radii forms a triangle with two equal sides — an isosceles triangle!
