This question has the power to shift mindsets in math. Those thinking narrowly about specific ... If an octagon had four right angles, walking around just those angles would bring us full circle: It ...

we need to know what fraction of the circle is shown. To do this, we use the angle and compare it with 360˚. This angle is 144°. That is \(\frac{{144^\circ }}{{360^\circ }} = \frac{2}{ ...

Just to be clear, I drew this triangle and then I measured the sides with a ruler—no math involved ... Since this is part of a circle, the arc-length would be (with the angle in measured ...
