Circle Theorems Notebook Teaching Resources 2 lessons, covering 9 rules including cyclic quadrilaterals, alternate segment theorem, tangents, angles in the same segment. with worked examples, practice question. Example 1: central angle theorem. find the measure of angle a a in circle d. d. recall the theorem. angle a a is an inscribed angle and is half the measure of the arc it intercepts. 2 solve the problem. arc pc pc is the intercepted arc of angle a. a. arc pc=42^ {\circ} pc = 42โ and angle a a is an inscribed angle.

This circle theorem activity covers: arc lengthmeasures of angles arcs involving central, inscribed, vertex inside, and vertex outside anglestangent segments and a radius (pythagorean theorem)segment lengths (two chords, two secants, secant & tangent)all equations are linear or quadratic where you can solve by taking the square root. They'll discover 4 of the circle theorems themselves, using a protractor and straightedge. for example, have your students draw 4 or 5 circles of all different sizes using a compass. then, direct them to place two points on each circle. have them draw two arc. they'll take time to do this for all their circles on their own in pairs, record the.
