Measuring Angles with a Protractor
Mr. Addit reviews right angles, acute angles and obtuse angles. He then measures a few angles. Next, he estimates the measurement of a couple angles and then measures to see how well he estimated.

What is the difference between an angle in radians and in terms of pie
👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

Determine the Measure of an Angle in Radians
👉 Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360...

How did Ancient Greek Philosophers Know the Earth was Round?
The Ancient Greeks had determined the planet was a sphere 2000 years before Columbus set sail for the New World, and they came up with estimates too! So how did the Ancient Greeks Philosophers work out that the Earth was a sphere and how...

Estimating Angles
Sometimes, exact measurements aren't necessary. Scholars learn to estimate the measure of angles by watching a useful video. The method employed here is to use 90-, 180-, and 270-degree angles as benchmarks, adding or subtracting as...
