Find the sum of the measures of the interior angles in an hexagon

Inscribed Angles - YourTeacher.com - Geometry Help

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.

Angles of Parallel Lines - Khan Academy

By 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 angles and lines. Good review for concepts of angles and vocabulary associated with angles. Good quality video. Good for middle elementary and middle school students.

Angles: Composition Measuring

By tiorico1

The instructor uses an electronic sketchpad to demonstrate how to constucut angles. Video discusses vocabulary and symbols associated with angles ray (sides of the angle) vertex (the point where the rays start). It then goes on to use the protractor to measure an angle. It starts with where to put one line of the angle and then where and what to measure. It also instructs students which set of numbers to use on a protractor. Then examples are measured. Good video for instruction and review for any grade level.

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

By 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.
