Inscribed Angles - YourTeacher.com - Geometry Help
By yourteachermathhelp
Students learn the definition of an inscribed angle, and that the measure of an inscribed angle is equal to ½ the measure of its intercepted arc. Students also learn the following theorems related to inscribed angles. If two inscribed angles intercept the same arc, then the angles are congruent. An angle inscribed in a semicircle is a right angle. If a quadrilateral is inscribed in a semicircle, then opposite angles are supplementary. The measure of an angle formed by a chord and its tangent is half the measure of the intercepted arc. Students are then asked to find the missing measures of arcs and angles in given circles using these theorems.

Angle bisector theorem proof | Special properties and parts of triangles | Geometry | Khan Academy
By Khan Academy
In this video, we'll quickly review the angle bisector theorem, and then we'll see how it's proven. We prove it by extending a parallel line to one of the triangle's legs. That tells us information about the interior angles!

By Khan Academy
One of the most important properties we need to know about inscribed angles is that the measure of an inscribed angle is half the measure of the central angle that subtends the same arc. This video shows us the meaning of that property and proves that it is actually true. If nothing else, this video will help you get better acquainted with inscribed angles and how we measure them.

Angles (part 3) | Angles and intersecting lines | Geometry | Khan Academy

This video uses an electronic black board with different colored pens. Angles formed with two parallel lines (defines parallel lines) and a transversal line (a line that crosses the two parallel lines). The video then goes into labeling the various angles, corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The last thing the video explains is that all the angles in a triangle add up to 180 degrees. It shows how to find the measurements of each of these angles. Good video for review of concepts and angle vocabulary. Good for middle school students.
