What is a 120 degree angle called

In this introduction we will quickly review angles. Angles are easy to use if you learn the basics about them. Number of degrees , Type of angle , Reason.

Note: Degrees can also mean Temperature, but here we are talking about Angles ). For example 90° means degrees.

This diagram might make it easier to remember: Also: Acute, Obtuse and Reflex are in alphabetical order.

The corner point of an angle is called the vertex.

And the two straight sides are called arms. The Obtuse Angles ClipArt gallery offers illustrations of angles ranging from degrees to 1degrees. An introduction to angles which covers naming angles , angle size, measuring angles and types of angles. So, the size of angle PQR is 1degrees. Well, that only leaves us with the angles between 1and 3degrees.

These angles are called reflex angles. Another way of saying this would be “ 1degrees is the supplement of degrees. Constructing 7 10 1, 13 1degree angles and more. Euclidean constructions with compass and straight edge (ruler).

The table shows angles that can be obtained by combining simpler ones in various ways. This point is called the vertex of the angle and the two rays forming the angle are called its arms or sides. Depending on the inclination between its two arms, an angle may be acute (less than degrees ), obtuse (more than degrees ) or . Different Angles have different names: types of angle. A Reflex Angle is more than 180° but less than 360°.

All the angles below are reflex angles : Reflex Angle Examples . One degree is divided into minutes (of arc), and one minute into seconds ( of arc). Use of degrees -minutes-seconds is also called DMS notation. Proof will show it works for all triangles.

You have probably heard of acute and obtuse angles. The easiest way to define an isosceles . I want to have the vertex once again at B. So this right over here is our point D. Learn how to draw acute, right, and obtuse angles with given points. You just have to have really accurate ways of measuring those small pieces of angles.

What would the angle be called if it was more than 1degrees.
