RS Aggarwal Solutions Class 7 Maths Chapter 15 Ex 15.2 – Overview
Exterior Angle of a Triangle
The exterior angle for any triangle can be defined as the angle which is formed at one side of the triangle and getting extended to its adjacent side. The rules applied while finding the exterior angles of a triangle are almost the same as what we do in the case of the interior angles for a provided triangle.
We can say this because every exterior angle comes with an interior angle by default the sum of the exterior angle and the interior angle ways come up as 180 degrees which forms a straight line.
Triangle Exterior Angle Theorem
The measure for every exterior angle for a given triangle will always be equivalent to the sum taken for the non-adjacent interior angles and the opposite interior angles. The two interior angles that are on the opposite side to the exterior angles are called the remote interior angles.
Properties Valid For The Exterior Angles
- The exterior angle for a given triangle will always be equivalent to the sum value that comes when any of the two opposite interior angles are asses to each other.
- The total sum is taken for the exterior angle and the interior angle will always be equivalent to the 180 degrees angle.
Importance of Solution and Revision Notes
- These are concise and easy to revise all the Chapters.
- From the examination point of view, a quick revision of notes helps to get the gist of the topic and refreshes the terminology in our minds.
- These notes cover all the formulas, theorems, and important equations, which makes it valuable to carry and study during exam time.
- These notes are prepared in such a way that a glance at the exam time can help to recall all concepts and formulas and save a lot of time during the last-minute preparation of the exam.
