The supplement of an 80 degree angle is an 100 degree angle.
78 degree angle
a 10-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.
66 degree angle
No
octogan
Since it is not a regular octagon, any value that you like.
Hint: 90/2=...
59 degree
180 degree angle or a straight angle
That is a regular octogan (8 sided shape)
Well, honey, you start by drawing a straight line with your compass. Then you put the pointy end of the compass on one end of the line and swing that bad boy until it hits the line at the desired angle. Voilà, you've got yourself a 56 degree angle. Keep on slaying those geometry problems, darling.
With a protractor
With a protractor.
First draw a 90 degree angle .Than draw a 20 degree angle from that 90 degree angle . Than the rest of the angle will be 90-20=70 .Now bisect the 70 degree angle we will get 70/2=35. Now add the rest of the angle means 35+20 =55 GOT 55 DEGREE ANGLE
The 8 interior angles of an 8 sided octagon add up to 1080 degrees
