Arcs are an important aspect of geometry, physics, trigonometry and design work. However, curved lines are much more difficult to measure than straight lines, which is why it's important to ...

A chord separates the circumference of a circle into two sections - the major arc and the minor arc. It also separates the area into two segments - the major segment and the minor segment. Calculate ...

In order to derive the formula to calculate the angle at the centre of the sector, the formulae for the arc length and area of a sector can be rearranged so that we can calculate the fraction of ...
