17 degrees is an acute angle because it's greater than 0 but less than 90 degrees.
The supplement of an 80 degree angle is an 100 degree angle.
78 degree angle

15 degrees. A bisected 60 degree angle makes 2 30 degree angles by definition of an angle bisector, then a 30 degree angle makes 2 15 degree angles by definition of an angle bisector.

The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.

An acute angle
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 243 degrees, which is in the third quadrant, the reference angle can be found by subtracting 180 degrees from it. Thus, the reference angle is 243° - 180° = 63°.
To layout a 45-degree angle, start by marking a point on your work surface where you want the angle to originate. Use a framing square or a protractor to measure a 45-degree angle from a reference line. If using a framing square, align one side with the reference line and mark along the other side to create the angle. Alternatively, you can draw a line from the point at a 45-degree angle using a compass to set equal distances from the reference line.
It is: 73+17 = 90 degrees
A 30 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
A reference angle is the positive angle less than 360 which is coterminal with the given angle. For a negative angle add 360 repeatedly until you gat an answer less than 360. =370 + 360 = -10 -10 +360 = 350

A 253-degree angle is an obtuse angle, as it measures more than 180 degrees but less than 360 degrees. It can be visualized as being located in the third quadrant of a circle, where angles range from 180 to 270 degrees. In terms of its reference angle, 253 degrees has a reference angle of 77 degrees, which is found by subtracting 253 from 360. This angle can also be used in various applications in geometry, trigonometry, and physics.
