## FAQs on RD Sharma Class 7 Maths Solutions Chapter 14 - Lines and Angles

**1. What is called an angle as taught in chapter 14 of class 7 RD Sharma Maths book?**

In the chapter on lines and angles, it is crucial for us to understand what angles actually mean. Students must get their doubts cleared on the topic. In simple words, an angle can be described as an angle is formed when two rays originate from one endpoint. There are several types of angles and they can be classified into several groups based on certain characteristics.

**2. What are the different types of angles as taught in chapter 14 of class 7 RD Sharma Maths book?**

The following types of angles are in the course which is mentioned below.

**Acute Angle:**When an angle is less than 90 degrees, it is an acute angle.**Obtuse Angle:**When an angle is more than 90 degrees but less than 180 degrees, it is an obtuse angle.**Right Angle:**When an angle is 90 degrees, it is a right angle. Straight Angle: When an angle is 180 degrees, it is a straight angle.**Reflex Angle:**When an angle is more than 180 degrees but less than 270 degrees, it is a reflex angle. Full Angle: When an angle is 360-degrees, it is called a full angle.

**3. What are “lines” as taught in chapter 14 of class 7 RD Sharma Maths book? **
