Angle basics and measurement
This tutorial will define what an angle is and help us think about how to measure them. If you're new to angles, this is a great place to start.
The naming of an angle is related to the line segments that create it. We'll also learn about the angle's vertex. Come on. Let's do this.
Let's come up with an exact way to measure an angle using a protractor. We'll also learn about acute angles. Not to be confused with augly angles :)
Let's use our virtual protractor to measure some angles together, shall we?
We're practicing measuring angles using the virtual protractor. Do this a few times with us and you'll use a real protractor like a pro!
Measure angles using a protractor.
We briefly discussed the types of angles in the last tutorial but we'll delve a little deeper into acute, obtuse, and right angles here.
Determine if an angle is acute, right, or obtuse. A protractor is provided.
Did you know that the measurement of an angle is realted to the arc of a circle? Yes, indeed! Watch.
We're slowly starting to put things together in this example exercise: angle, circle, circumference, and fractions. Woohoo!
Estimate and compare angle measures in situations.
