# Adina is constructing a line perpendicular to YJ←→. She has already constructed two arcs as shown. She moves her compass point to Y to construct an arc above the line. What must be true about the width of Adina’s compass opening before she draws the arc?

IT must be wider

The two arcs will not meet at C if the compasses are smaller. If they are the same, they will meet there.

The width of Adina's compass opening must be greater than half the length of the line segment YJ.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
