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°.

This angle lets us define a portion of the circle's circumference (an arc) or a portion of the circle's area (a sector ). sector arc center central angle. The number of degrees of arc in a circle is 360 360.
WebTheorem 3: Angles from the same chord in the same segment are equal If we have two triangles inside a circle with all three corners touching the circle, and the triangles share a side (also known as a common chord) then the third angle is the same in both triangles, as long as these third angles are in the same segment.
