WebA tangent makes an angle of 90 degrees with the radius of a circle, so we know that ∠OAC + x = 90. The angle in a semi-circle is 90, so ∠BCA = 90. The angles in a triangle add up to 180, so ∠BCA + ∠OAC + y = 180 … Web18 uur geleden · Circle theorems can be used to solve more complex problems. curriculum-key-fact When calculating angles using a circle theorem, always state which …

WebIn this unit we will revisit learners' understanding of angles and the angle facts they may need in solving multi-step geometrical reasoning problems. The lessons then build on this to make sure learners understand the link between these angle facts and the circle theorems and can confidently apply a range of facts to derive the circle theorems.
