Why is the sum of angles in a quadrilateral equal to 360 degrees?
A quadrilateral can be divided with a diagonal into two triangles each with an interior angle sum of
It really depends upon how far back you want to go for this proof.
If you accept that the interior angles of a triangle add up to If you need to prove that the interior angles of a triangle add up to
you can use the rule that the interior angles on the opposite sides of a line crossing two parallel lines are equal.

The sum of angles in a quadrilateral is equal to 360 degrees because a quadrilateral can be divided into two triangles, each of which has a sum of interior angles equal to 180 degrees. Therefore, the total sum of the interior angles in a quadrilateral is twice that of a triangle, which equals 360 degrees.

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.
