Radian and degree | Unit circle definition of trig functions | Trigonometry | Khan Academy
By Khan Academy
This video explains what a radian is and how we determine the radian measure of an angle. The key point here is that the radian measure of an angle is the length of the arc (in radius lengths) cut off by that angle (if the angle's vertex is on the center of the circle). You may ask: Won't the size of the circle affect the radian measure of an angle? A key feature of circles is that they are all similar (and thus, proportional). When we account for their larger size, we take into account the larger radius. As a result, the radian measure is the same for all circles (since the radian measure is how many radius lengths long the arc is).

Metric Unit Conversions - YourTeacher.com - Pre Algebra Help
By yourteachermathhelp
Students learn that in the metric system all measures of length are based on meters. For example a centimeter is 1/100 of a meter. And all measures of weight are based on grams. For example a kilogram is 1000 grams. And all measures of volume are based on liters. For example a milliliter is 1/1000 of a liter. Students are then asked to solve problems using conversion factors such as 4 500 milligrams = ____ grams.

Median of a Triangle | MathHelp.com
By MathHelp.com
This lesson covers math ratios. Students learn that the ratio of one number to another is the result of the first number divided by the second number. Given various figures, students are then asked to determine ratios of side lengths or angle measures. Students are also given word problems involving ratios.
