No, an acute isosceles triangle cannot have two angles that measure 40 degrees. In an isosceles triangle, the two equal angles must be greater than the third angle. Since the sum of the angles in any triangle is 180 degrees, and an acute triangle has all angles less than 90 degrees, having two angles of 40 degrees each would make the third angle less than 100 degrees, violating the condition for an acute triangle.

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.
