## FAQs on RS Aggarwal Class 7 Solutions Chapter-15 Properties of Triangles

**1. What are the Concepts that are Extensively Covered in the RS Aggarwal Class 7 Exercise 15?**

The chapter The Triangle and its Properties introduce the properties of the triangle to the students of Class 7. Students learn about the terms such as medians and altitudes of a triangle. The properties of triangle studied are-

Exterior angle property of a triangle.

Angle sum property of a triangle.

Properties of an equilateral and isosceles triangle.

Properties of Right-angled triangle.

Pythagoras theorem.

Students can practice problems based upon these concepts from RS Aggarwal Class 7 Maths Chapter 15. It includes direct questions where you will be asked to find the missing values when some are given. It also includes word problems where you will have to draw diagrams and change the problem into a mathematical equation.

**2. What are the Types of Questions Asked from the Chapter in the Examination?**

Questions are based upon the properties of the triangle. Students will have to find some missing information based upon the values given. The questions can be based upon the exterior angle property or the angle sum property or a combination of both. Questions will be asked upon the properties of the median and altitudes of the triangle. Specific problems can be asked on special triangles such as the equilateral triangle or isosceles triangle. Questions based upon the Pythagoras theorem are commonly asked in the examination. Students will be asked to find the length of the sides of the triangle using the properties of the right-angled triangle.

**3. What are the Key advantages of the RS Aggarwal Solutions Class 7 Maths Ch 15 by Vedantu?**

**4. What is a triangle and explain its types following the concepts explained in RS Aggarwal class 7 chapter 15?**

Triangle is a closed figure with three angles, which can be otherwise written as a closed figure having three sides. Triangle can be classified via 2 major ways, one on the basis of angle and other on the measurement of sides.

**On the basis on angle:**

Acute Angled triangle

Oblique Angled triangle

Right Angled triangle

**On the basis of the measurement of sides:**

Scalene triangle

Isosceles triangle

Equilateral triangle

**5. Following the concepts explained in RS Aggarwal class 7 chapter 15, what are the properties of a triangle?**

Here are some of the properties of triangles provided in chapter 15 of RS Aggarwal of class 7 -

All triangles have no more or less than three angles, three sides and three vertices.

Sum of all the interior angles in a triangle is equal to 180 degrees. It is named as the Angle sum property of a triangle.

The side opposite the largest angle is going to be the largest side of that triangle.

Exterior angle property of a triangle, any angle of a triangle is equal to the sum of the opposite interior angles.
