What is the measure of arc AB?

Thus, the length of the arc AB will be 5/18 of the circumference of the circle, which equals 2πr, according to the formula for circumference. length of arc AB = (5/18)(2πr) = (5/18)(2π(18)) = 10π. Thus, the length of arc AB is 10π.

How to copy ∠BAC with a compass?

Let us say that you are given ∠BAC that you are supposed to copy. Draw a line PQ. Point P is the vertex of the copied angle. Place the compass pointer at point A and make an arc which cuts arms AC and AB at points K and J respectively. Without changing the radius of the compass, cut an arc on PQ at point M.
