Question

is this angle acute, right, obtuse, or straight?

Explanation:

Step1: Recall angle - type definitions

An acute angle measures less than 90 degrees, a right - angle measures 90 degrees, an obtuse angle measures more than 90 degrees but less than 180 degrees, and a straight angle measures 180 degrees.

Step2: Analyze the given figure

The two lines in the figure are parallel and do not form an angle between them. Since there is no angle formed, we cannot classify it as an acute, right, obtuse, or straight angle. But if we consider the concept in terms of the non - existent angle between the parallel lines, we can say that the "angle" is 0 degrees (in a sense of the angular separation), which is less than 90 degrees.

Answer:

Acute
