# NCERT Solutions Class 7 Maths Chapter 5 Lines and Angles

Geometry is the branch of mathematics that studies the properties of planar figures such as points, lines, planes, and solids. The NCERT solutions for class 7 maths chapter 5 focuses on the geometrical concepts of the points, lines, rays, the kind of angles that the lines form. Also, the kind of angles that the lines make when they intersect each other, like interior, external, corresponding, vertically opposite, and the properties that they possess, all of these are explained in the NCERT class 7 maths chapter 5 Lines and Angles.

The important facts about the lines and the angles, as the chapter name suggests, are that a line has no endpoints as compared to a line segment that has two endpoints. And about the angles, an important thing to remember is that the angles that sum up to ninety degrees are complementary while those that sum up to 180 degrees are supplementary. More such concepts can be read in the class 7 maths NCERT Chapter 5 Lines and Angles pdf files provided in the links below and also find some of these in the exercises given below.

## List of Formulas in NCERT Solutions Class 7 Maths Chapter 5

Geometry starts with a point, leading to the line segment and a line, and then these lines forming angles. Angles form a major part of studying geometry. The two most important concepts that will help the students solve the problems related to the angles are the complementary and supplementary angle definitions that will help frame the formulas if unknown angles are asked to be found out in the questions. The NCERT solutions class 7 maths chapter 5 explains this concept as :

**Complementary Angles: Angle A + Angle B = 90 degrees****Supplementary Angles: Angle A + Angle B = 180 degrees**
