The 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°. See more First off, a definition: A and C are "end points" B is the "apex point" Play with it here: When you move point "B", what happens to the angle? See more Keeping the end points fixed ... ... the angle a° is always the same, no matter where it is on the same arcbetween end points: (Called the … See more A tangent linejust touches a circle at one point. It always forms a right angle with the circle's radius. See more An angle inscribedacross a circle's diameter is always a right angle: (The end points are either end of a circle's diameter, the apex point can be anywhere on the circumference.)
