# NCERT Solutions for Class 7 Maths Chapter 5: Lines and angles The line is a straight dimensional figure that extends endlessly to both sides. Angles are formed by two rays meeting at the common endpoint. In Ex 5.1, you will learn about complementary angles, supplementary angles, adjacent angles, linear pair and vertically opposite angles. When The sum of two angles is 90 degrees, it is known as Complementary angles, and when the sum of two angles is 180 degrees, it is said to be supplementary angles.

When the angels have a common aim, and a common vertex but no common interior points are known to be adjacent angles. In Ex 5.2 there are topics related to lines like intersecting lines, transversal and angles made by a transversal, a transversal of parallel lines, etc. The transversal line is a line that intersects two or more lines at a distinct point. This chapter includes a topic like:

• Introduction to lines and angles
• Related Angles- Complementary angles, supplementary angles, adjacent angles, linear pair and vertically opposite angles
• Pairs of lines
• Intersecting lines, transversal, angles made by transversal and transversal of parallel lines.
• Checking of parallel lines
