How many acute angles can a quadrilateral have?
Wyatt AndersonThe sum of the internal angles of a quadrilateral is
Hence the maximum number of acute angles a quadrilateral can have is
In the following picture, the red square has no acute angles, the green kite has one acute angle, the blue rhombus has two and the gold kite has three.

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.
