The vocabulary used in mathematics is just as important as the content studied in mathematics. There are a number of terms that are specific to the study of mathematics, and there are also terms that are used in everyday language that have a different meaning when used in the context of ma...

The value of pi in degrees is equal to 180°. Here the concept of radian will help us understand this. Radian is the SI unit for measuring angles. One radian is defined as the angle that is subtended from the center of a circle that intercepts an arc that is equal in length to the...
How do we prove that the measure of an inscribed angle (of an intercepted arc) is half of the central angle (or the measure of the intercepted arc)? What is an example of group polarization? What is inequality in society? True or False: If two corresponding angles of two triangles are...
where {eq}\mathrm{atan2} {/eq} is the two-argument arctangent function. The resulting azimuth angle is measured in radians, clockwise from north as before. Become a member to unlock this lesson Lesson Summary Register to view this lesson ...
Pi is a special number in mathematics that's typically rounded up to 3.14. (In actuality it's an irrational number with an infinite number of decimal places, but you don't have to worry about that unless you want to delve into a separate explainer on irrational numbers.) Example: Circle...
In mathematics, perpendicular lines are two straight lines that meet or intersect at 90°. This intersection is also called a right angle and is marked by a small square as shown in the figure below: Perpendicular Definition and Origin The definition of perpendicular is a straight line at an ...
As well as the names, children need to know the properties of 2D shapes as listed below and in the printable table. Circles A circle has 1 curved side A semi-circle has 2 sides; 1 curved side and 1 straight side. The full arc is a 180° angle. Triangles (3-sided shapes) An equ...
In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. Intuitively, a curve may be thought of as the trace left by a moving point. Arc (Mathematics) A segment of a circle. Curve A line that deviat...
