## FAQs on RD Sharma Class 7 Maths Solutions Chapter 15 - Properties of Triangles

**1. What are the important Properties of a Triangle discussed in this Chapter?**

In the Chapter, several important concepts on Triangles have been discussed. Students need to understand the following Properties clearly as it captures the essence of the Chapter. The important Properties of a Triangle which are discussed in this Chapter are:

Angle sum property

Exterior angle property

The third side is always lesser than the sum of the lengths of two sides of a Triangle

Pythagoras theorem

**2. What are the three main types of Triangles generally?**

In the Chapter, we have seen several types of Triangles based on several criteria. The three main types of Triangles are based on the length of the sides are:

Equilateral Triangle

Isosceles Triangle

Scalene Triangle

There exist right-angled Triangles too which can either be isosceles or scalene but they can never be scalene.

**3. What are the parts of a Triangle?**

There are three main parts to a Triangle that make it a Triangle. The three parts of a Triangle are:

Vertices

Sides

angles

A thorough understanding of the three parts and their roles are crucial to solving questions on Triangles.

**4. What is the Pythagoras theorem?**

The Pythagoras theorem is the most important theorem in geometry. We can prove a lot of things using this theorem. We can find the length of one side of a Triangle using the theorem if the length of the other two sides is unknown. The theorem is named after the Greek Philosopher who discovered it, Pythagoras. The theorem says that the square on the hypotenuse = sum of the squares of the legs.
