WebThe Angle in the Semicircle Theorem tells us that Angle ACB = 90° Now use angles of a triangle add to 180° to find Angle BAC: Angle BAC + 55° + 90° = 180° Angle BAC = 35° So there we go! No matter where that angle is on the circumference, it is always 90° Finding … Tangent Lines and Secant Lines (This is about lines, you might want the tangent … WebCircle theorems are properties that show relationships between angles within the geometry of a circle.
