Angle types review (article) | Angles | Khan Academy
Review the following types of angles: acute, right, obtuse, and straight. Identify and draw types of angles in some practice problems.
Angles: introduction (video) | Angles | Khan Academy
In high school geometry and trigonometry, angle operations become more diverse. You use a compass, straightedge, and a protractor to construct and analyze angles.
Angle basics (practice) | Measuring angles | Khan Academy

Angle basics review (article) | Khan Academy
What is an angle? An angle is two rays that share a vertex . Intersecting lines or line segments also form angles.
Angles, parallel lines, & transversals (video) | Khan Academy
When a third line, called a transversal, crosses these parallel lines, it creates angles. Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each …
Measuring angles in degrees (video) | Angles | Khan Academy
So maybe the measure of angle XYZ should be larger than the angle of the BAC, and that is exactly the way we think about the measures of angles. But what I want to do in this video is come up with an …
Angles | Lesson (article) | Geometry | Khan Academy
Angles are measured in degrees (∘ ), which describe how spread apart intersecting lines or line segments are. Narrow spreads have small angle measures, while wide spreads have large angle …
