In this unit we are going to learn about Complementary angles, supplementary angles. We say that the angle is formed, if the two rays goes in the different directions and have the same starting point. This starting point is called the vertex of the angle. Now we will see what complementary angles are and what are supplementary angles? Moreover we will study that what is the complement of the given angle and what is the supplement of the given angle. (know more about cbse class 12 board papers, here)
We mean, by the term Complementary angles, we mean that the sum of two angles is equal to 90 degree. If the measure of one angle is given say x and we need to find the Complement of the given angle then we say that the complement of the given angle is 90 – x. Thus if the two angles are complementary, it means that their sum is 90 degrees and so it forms a right angle. The two adjacent angles if joined together if form a right angle, and then we say the two angles are complementary.
We mean, By the term supplementary angles, we mean that the sum of two angles is equal to 180 degree. If the measure of one angle is given say x and we need to find the supplement of the given angle then we say that the supplement of the given angle is 180 – x. Thus if the two angles are supplementary, it means that their sum is 180 degrees and so it forms a straight angle. We also observe that if the two angles are supplementary, then their sum is 180 degrees and so we can say that the two angles form a linear pair. In the next session we will discuss about Tessellations.
