<li>If two inscribed angles mark off the same arc, the angles are equal in size.</li>
<li>If an inscribed and a central angle mark off the same arc, the central angle is double the size of the inscribed angle.</li>
<li>If the end points of a central angle can be connected with a diameter, the central angle is a right angle.</li>
<li>The angle between a radius and a tangent is a right angle.</li>
<li>The angle between the tangents drawn at the end points of two radii, and the angle between the radii make up a straight angle.</li>
</ul>
