Angles on the circumference

In this video I'm going to show you the angles on the circumference. An angle can occupy different positions on the circumference and they are the central angle, the inscribed angle and the semi-inscribed angle.

The central angle is the one that has its vertex in the center, its sides contain two radii. The width of the central angle is that of the arc it covers. In short, it is that the vertex has to be in the center.

In the inscribed angle keep in mind that the vertex has to be at a point and that its sides are chords. That the bristles are straight that cross the circumference at the center.

Finally, the semi-inscribed angles, which has the characteristics that its vertex is a point on the circumference and its sides contain a chord and a tangent line.

Also, if you want to learn more about the performing angle exercises on the circumferences, follow the video carefully and if you still have doubts you can do the printable exercises with their solutions that I have left you on the web.
