Well there are many ways to name an angle. You can look up cute angle names on the Internet (Pun intended), or you can take another angle and go to you local bookstore which has many nice name books. You can look in the phone book but not just any, you should look in the right angle phone book for nomenclature ideas. Some people just look around at their friends and see what they named their angles. Or if you are very original you can make up an angle name like apple angle. Seriously, you can name an angle by specifying three points: two on the rays and one at the vertex
obtuse,cute,right,and straight angles
The 5 ways to prove that two triangles are congruent are to find equal: 1) side-side-side 2) side-angle-side 3) angle-side-angle 4) angle-angle-angle 5) hypotenuse-leg
Acute angle: greater than 0 but less than 90 degrees Right angle: exactly 90 degrees Obtuse angle: greater than 90 but less than 180 degrees Reflex angle: greater than 180 but less than 360 degrees

The VERTEX of the angle is always in the middle... so if it is angle ABC, then you can also name it CBA as long as the vertex letter is in the middle, usually there are only 2 ways to name an angle.Also, if there aren't any other angles with the same vertex, you can just call angle ABC, angle B.Summary: If you have an angle:the vertex is labeled B, the others are A and C. what can you call the angle?Answer: ABC,CBA or B
obtuse,cute,right,and straight angles
Acute, Obtuse, Straight, and Right are the four types of angles.
For example, you might name an angle as "ABC", where "B" is the vertex, and "A" and "C" are points lying on the sides of the angle. If there are additional points on the same sides, you can substitute those points instead.
No, you cannot find the exterior angle before the interior because the interior angles can vary in many ways.

When constructing a right angle triangle which has a 90 degree angle and two acute angles.
If it's for an angle (triangles included) you can only write it 2 ways: XYZ and ZYX
There are many ways to measure a contact angle, but the simplest way is to use a goniometer. The image of the droplet is taken with a high resolution camera; the angle can then be measured using a protractor.
