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
A 190 degree angle is a reflex angle.
Well, honey, a 190-degree angle is called an obtuse angle. It's bigger than a right angle but not quite as dramatic as a straight angle. So, if you ever come across a 190-degree angle, just remember it's too sassy to be acute but not quite obtuse enough to be a full 180.
In order to make a 190 degree angle, you should subtract 190 from 360. This gives you 170. Draw this angle, and the outer angle is the 190 degrees that you need.?æ
Oh, dude, that's an obtuse angle! It's like when you have a really big angle that's more than 90 degrees but less than 180 degrees. So, when you hit the 190-degree mark, you're officially in the obtuse club. Like, congrats on being so... obtuse.
An angle of 190 degrees is a reflex angle
A reflex angle
A reflex angle is one that is more than 180 degrees but less than 360 degrees. If the reflex angle measured 190 degrees, then there would be a 170 degree, or obtuse, angle opposite it. If the reflex angle measured 270 degrees, then there would be a 90 degree, or right, angle opposite it. If the reflex angle measured 300 degrees, then there would be a 60 degree, or acute, angle opposite it. It helps to draw or picture these angles as sectors of a circle.
No, it is a reflex angle
It is 10 degrees more than a straight line so its a reflex angle.
No, because a triangle's angles can only measure up to 180 degrees. A right angle is 90 degrees, plus another 100 degree angle would be 190 degrees.
