In the previous post we have discussed about Point and In today's session we are going to discuss about Types of Angles. By the term angle, we mean the distance in degrees between the two rays, which have the same vertex. There are different Types Of Angles.
Let us take them one by one. The angles are classified based on the measure of the angles.
1. Acute Angle : We say that the angle is an acute angle if we have the measure of the angle less than 90 degrees.
2. Right Angle : If we have the measure of the angle equal to 90 degrees, then we say that the angle measure is a right angle.
3. Obtuse Angle : If the angle measure of the angle is greater than 90 degrees and the measure ls less than 180 degrees, then we say that the angle is obtuse angle.
4. Straight Angle : If the measure of the angle is 180 degrees, then we say that the angle is a straight angle. It simply forms a straight line by the two arms of the angle.
5. Reflex angle: All the angles with the measure of greater than 180 degrees and less than 360 degrees, then we say that the angle is a reflex angle.
6. Complete Angle: Any angle measure of 360 degrees is called the complete angle. (know more about Angle, here)
We come across the terms complementary angles and the supplementary angles : If the sum of the two angles is equal to 90 degrees, then we say that the two angles are complementary. On the another hand we say that if the measure of the two angles sum up to 180 degrees, then it is the pair of complementary angles.
To learn about the Average Speed Formula, we can take the help of online tutor for math which can help us to clear the concepts. Icse 2013 Solved Papers are also available online, which the students can download and understand the concepts.
