Circles and circle theorems
Did you know?
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 … WebCircle theorems are statements in geometry that state important results related to circles that are used to solve various questions in geometry. Circle theorems in geometry are related to the various …
