Measuring Angles With a Protractor
This short video demonstrates how to use a protractor to measure the degree of an angle with step-by-step instructions. (1:40)
Angles of Parallel Lines - Khan Academy Angles of a transverse line when you intersect parallel lines are discussed in this video. Video discusses parallel lines and what a transverse line is. Video then goes into labeling the angles, such as corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The video shows how to find the measurement of each of the angles using what you know about

This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)
Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc.

Lose Yourself in the Digits - Song
This music video is to the tune of Eminem's "Lose Yourself" and teaches about the concept of Pi. Lyrics are not included on the screen but can be found at www.teachpi.org. The lyrics in the chorus are, "You better lose yourself in the digits of pi. It's a high but you got a thousand more to go. The numbers do not stop or drop into pattern, no. To memorize it would take most of a lifetime." (04:26)
