Because if this angle was able to be exactly 90 degrees it would be a right angle if it was less than 90 it would be acute.The last one which is key to a lot of proofs is a straight angle. So again you can label an angle two different ways, one using three letters that make up the two sides and the vertex making sure that your vertex is the middle letter or if there aren't any other adjacent angles you can just label it based on its vertex.There are four key types of angles first one is a acute, so if I drew this angle and I said that's angle x if it is acute that means that is less than 90 degrees but also greater than 0 degrees. Angles can be named in three ways: 1. And the way that will always work is using three letters. 1 . E. 3 G. D E. 7) 8) F G J. Get Better Our printable worksheets are meticulously designed for children of grade 4 and grade 5. The vertex is this point that is the common end point of your rays.

It's measured in degrees and is between 0 and 180 degrees, if it's over 180 then you're going to subtract that number. ∠ABC or ∠CBA 2. 5) E C 3 D 6) E G F 4 7) G E F 1 8) H J 3 I Draw and label an angle to fit each description. So I'm going to label this as the vertex, so the rays form what are called the sides. So 2x=360 degrees.So keep this in mind and remember obtuse is going to be in between 180 and 90, right is going to be exactly 90, acute is going to be between 90 and 0. The middle letter is called the VERTEX of the angle. You need to figure out the missing one. Univ. Naming Angles Using Three Points.
