# How do you find the positive acute angle?

##### 1 Answer

#### Answer:

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

#### Explanation:

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*).

Once these decisions are made, we can talk about *positive* angles (those with counterclockwise rotation) and *acute* angles (those measured less than
