The speaker explains how to recognize and apply the angle properties created by chords connecting with the center and tangents running outside of the circle. The first theorem is the arrow shape, where the angle at the center is always double the angle at the circumference. The second theorem is the bow shape, where angles in the same segment are equal. The third theorem is the quadrilateral, where opposite angles of a cyclic quadrilateral equal 180 degrees. The fourth theorem is the semicircle, where the angles in a semicircle always equal 90 degrees, making the diameter a hypotenuse.\n
