##### About 7 Maths Chapter 5

In 7 Maths Chapter 5 Lines and Angles, we will study about various types of angles and their applications. We already know that a line segment has two end points. If we extend the two end points in either direction endlessly, we get a line. Thus, we can say that a line has no end points. On the other hand, a ray has one end point (starting point). An angle is formed when lines or line segments meet. Study about the following angles:

*Complementary angles*: When the sum of the measures of two angles is 90°, the angles are called complementary angles.*Supplementary angles*: The sum of the measures of the two angles comes out to be 180°, then such pairs of angles are called supplementary angles.*Adjacent Angles*: Angles having a common vertex, a common arm and the non-common arms are on either side of the common arm are called adjacent angles. Adjacent angles have a common vertex and a common arm but no common interior points.*Linear Pair*: A linear pair is a pair of adjacent angles whose non-common sides are opposite rays.*Vertically Opposite Angles*: when two lines intersect, the vertically opposite angles so formed are equal.

- 2 ऐसा कोण ज्ञात कीजिए जो अपने संपूरक के समान हो।
- 3 Can two angles be supplementary if both of them are acute.
- 4 क्या दो ऐसे कोण संपूरक हो सकते हैं यदि उनमे से दोनों अधिक कोण हैं?
- 5 Fill in the blank: If two adjacent angles are supplementary, they form a _______________.

#### Find the angle which is equal to its complement.

Therefore, x + x = 90

or 2x = 90

and x = 90/2 = 45

Thus, 45 is equal to its complement.

#### ऐसा कोण ज्ञात कीजिए जो अपने संपूरक के समान हो।

इसलिए, x + x = 180 [संपूरक कोण] 2x = 180

x = 180/2 = 90

अतः, 90 का कोण अपने संपूरक कोण के बराबर है।
