# Radian and degree | Unit circle definition of trig functions | Trigonometry | 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).

# Measuring to the Nearest Quarter inch

## By Skubes ed

Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.

# Measuring Area in Square Units

## By Skubes ed

. A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.
