This happens at each corner until you have returned to your starting point. At this point, you are now facing the same direction you started with, having turned through a full circle. A full circle is 360°, hence all of the exterior angles must sum to 360°. This is the same regardle...

A tangent to a circle is perpendicular to the radius drawn to the point of tangency. When two segments are drawn tangent to a circle from the same point outside the circle, the segments are equal in length. The following figures show the Inscribed Angle Theorems and Angles in Circle Theorem...

adjacent side and opposite side. This only defines the sine, cosine and tangent of an acute angle. The sine, cosine and tangent are also defined for non-acute angles. To give the full definition, you will need the unit circle. However, in a right triangle, all angles are non-acute, an...
Two or more angles on a straight line add up to 180°. In the diagram above, the circle to the left is split into three sectors the angles of the green and white sectors are both 90°, adding up to 180°. The figure to the right shows that angles a and b also add up to 180°...
