138.7-degree angle (138.7° angle)

138.7-degree angle

What kind of angle is a 138.7-degree angle? What does a 138.7-degree angle look like? Here we will explain how to determine what kind of angle a 138.7-degree angle is, and also illustrate what a 138.7-degree angle looks like. Let's start by defining the six types of angles:

Acute: < 90°
Right: = 90°
Obtuse: > 90° & < 180°
Straight: = 180°
Reflex: > 180°
Complete: = 360°

138.7° is greater than 90° and less than 180°. Therefore, a 138.7-degree angle is an obtuse angle.

To illustrate what a 138.7-degree angle (138.7° obtuse angle) looks like, we drew the image below.

To create a 138.7-degree angle, we started at the horizontal line, which is called the initial side, and then turned 138.7° counter-clockwise towards the terminal side. Note that we shaded the 138.7-degree angle region in blue, and the two sides are connected at what we call the vertex.
