# How do you find the positive acute angle?

*Positive acute* angles are those measured counterclockwise from initial to final position of the ray and whose size is less than *right* angle.

An angle is a part of a two-dimensional plane located between two rays that share the origin.

When we want to measure angle, we usually measure the rotation needed to transform one of those boundary rays into another. That means, that the proper measurement can be achieved if we (a) choose which ray is the beginning and which is the ending position of a rotation, (b) choose one of two directions (counterclockwise, considered positive, or clockwise, considered negative).

To find the positive acute angle between two lines, you can use the formula:

[ \text{Angle} = \cos^{-1} \left( \frac{{\text{dot product of the two lines}}}{{\text{product of their magnitudes}}} \right) ]

In this formula, the dot product of the two lines is the sum of the products of their corresponding components, and the product of their magnitudes is the product of the magnitudes of the two lines. Use the inverse cosine function to find the angle in radians.

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.
