About 7 Maths Chapter 5

In 7 Maths Chapter 5 Lines and Angles, we will study about various types of angles and their applications. We already know that a line segment has two end points. If we extend the two end points in either direction endlessly, we get a line. Thus, we can say that a line has no end points. On the other hand, a ray has one end point (starting point). An angle is formed when lines or line segments meet. Study about the following angles:

  • Complementary angles: When the sum of the measures of two angles is 90°, the angles are called complementary angles.
  • Supplementary angles: The sum of the measures of the two angles comes out to be 180°, then such pairs of angles are called supplementary angles.
  • Adjacent Angles: Angles having a common vertex, a common arm and the non-common arms are on either side of the common arm are called adjacent angles. Adjacent angles have a common vertex and a common arm but no common interior points.
  • Linear Pair: A linear pair is a pair of adjacent angles whose non-common sides are opposite rays.
  • Vertically Opposite Angles: when two lines intersect, the vertically opposite angles so formed are equal.
