NCERT Solutions for Class 9 Maths Chapter 6: Points To Remember

While studying, the important points to remember from Class 9 Science are as follows:

An angle is formed by intersecting two non-collinear rays with a common starting point.
A right angle is defined as an angle with a measurement of 90°.
An acute angle is one with a measure of less than 90°.
An obtuse angle has a measure greater than 90° but less than 180°.
A straight angle is one with a measurement of 180°.
If the sum of two angles is 180°180°, they are supplementary.
If the sum of two angles is 90°90°, they are complementary.
A reflex angle measures more than 180°.
If the non-common arms of two adjacent angles are two opposite rays, they are said to form a linear pair of angles.
When two lines intersect, the angles that are vertically opposite are equal.
