What kind of angle is 120

Acute angles are less than 90 degrees, obtuse angles are more than 90 degrees, and right angles are exactly 90 degrees. Angles such as degrees which are more than but less than degrees are called reflex angles. Drawing angles, angle measurement need a protractor.

When using three points to name the angle, always put the name of the vertex in the middle. Be careful when naming an angle that shares a common vertex with other angles. Vertex: The common end point at which the two rays meet to form an angle is called the vertex. We can find angles in various things around us, such as in a pair of scissors, a hockey stick, a chair. In an isosceles triangle the vertex angle is half the base angle. What is the vertex angle?

Explanation: Every triangle has degrees. A vertex angle in a polygon is often measured on the interior side of the vertex. The space formed when two rays meet each other at a common point is called an angle. Angles can be classified both on their measurement and the way they are rotated. Based on the measurement, angles are classified as follows.

Observe the following figure to relate to the different kinds of angles explained below. The angle formed by the ray s PQ and QR in the figure is an obtuse angle. At a straight angle, the two rays are opposite to each other.

A straight angle can be formed by combining two adjacent right angles or in other words two right angles make up a straight angle. The next type of angles is based on the direction of rotation of one arm of an angle. When two lines intersect and meet at a point, an angle is formed. Let us discuss the angle types on the basis of rotation.

Positive angles are the ones in which angles are rotated from the base in the counter-clockwise or anti-clockwise direction. Negative angles are the ones in which angles are rotated from the base in the clockwise direction. For two angles to be adjacent angles , the following conditions should be true.

Here, one angle is the complement of the other angle. So these two angles are said to be supplementary. Here, one angle is the supplement of another angle. When a line or a transversal passes through two parallel lines the angles formed at the opposite sides of the line or the transversal are called alternate interior angles which are equal. It is an obtuse angle. Obtuse angle. An isosceles triangle. An angle that is degrees would be considered an "obtuse" angle.

This is because its angle measurements exceed 90 degrees. Anything under 90 would be considered "acute". If its a regular polygon and each inside angle is degrees then it is a 6 sided hexagon.

The angle is degrees. The last angle would have to be 60 degrees as well. Log in. Math and Arithmetic.
