#### RS Aggarwal Class 9 Solutions Chapter 8 – Triangles

##### What are Properties of a Triangle:

- The Perimeter of a Triangle: ½ × Length × Breadth.
- The area of a triangle is the sum of all three sides.
- Internal Angle: 60°.
- 180° is the sum of all the internal angles.

##### What are Different kinds of triangles:

You can tell the difference between triangles by:

- According to the length of the sides
- According to the measure of internal angles

**Based on the length of the sides:**

It is a triangle with three sides that are all the same length. All of the angles inside are 60°. Let’s say a triangle has three sides labeled a, b, and c.

- Equilateral Triangle: a = b = c
- Isosceles Triangle: It has two sides that are the same length and one side that is not.
- Isosceles Triangle: a = b, but not c
- Scalene Triangle: It has sides that are not all the same length, so each side is a different length. All of the angles have different lengths as well.

**Based on the size of the internal angles:**

- Right Angle Triangle: A right triangle is a triangle with one interior angle that is 90°.
- Pythagoras’s Theorem, which says that a2 + b2 = c2, is true for right angles. Where a, b, and c are any triangle’s sides.
- Obtuse Triangle: An obtuse triangle is a triangle with an angle inside that is greater than 90°.
- Acute Triangle: An acute triangle is a triangle with angles inside that are less than 90°.

**Inequalities in a Triangle:**

- 1st Theorem: If two sides of a triangle are not the same length, the angle opposite the side that is longer is bigger (or greater).
- Second Theorem: Any triangle has a side that is longer than the angle that is bigger.
- Third Theorem: Any two sides of a triangle add up to more than the third side.

#### Exercise by discussion of RS Aggarwal Solutions for Class 9 Chapter 8
