RD Sharma Class 7 Solutions Chapter 15 - Properties of Triangles (Ex 15.3) Exercise 15.3

Every geometric shape has a set of fixed attributes that define the relationship between various sides and angles. The main triangle properties given below will be studied in RD Sharma Class 7 Solutions Chapter 15 - Properties of Triangles (Ex 15.3) Exercise 15.3 PDF.

• There are three sides, vertices, and angles in a triangle.

• The total of a triangle's three internal angles is always 180 degrees, according to the angle sum property. For example, angle P + angle Q + angle R = 180° in any triangle PQR.

• The length of the two sides of a triangle is greater than the length of the third side, according to the triangle inequality property.

• According to the Pythagorean theorem, the square of the hypotenuse of a right triangle equals the sum of the squares of the other two sides, i.e. (Hypotenuse² = Base² + Altitude²).

• The longest side is the one on the opposite side of the bigger angle.

• The exterior angle of a triangle is always equal to the sum of the interior opposing angles, according to the exterior angle property of a triangle.

The properties of triangles and how they are differentiated, as well as the key fact that the sum of the angles of any given triangle is equal to 180 degrees, are the main takeaways for students from the class 7 maths RD Sharma solutions chapter 15 The Triangle and its Properties. This will be very useful in answering problems in the exercises that can be obtained from the pdf links below, and you can also find some of these in the exercises that are listed below.

• All of the angles in a triangle must be more than or equal to 60 degrees.

• A triangle is a closed three-sided shape.

• Heron's formula and Pythagoras theorem are two significant formulas relating to triangles.

• The sum of a triangle's angles is 180°, which is written as 1 + 2 + 3 = 180°.
