Important Questions on Class 7 Maths Chapter 5
Find the angle which is equal to its complement.
Let one of the two equal complementary angles be x Therefore, x + x = 90 or 2x = 90 and x = 90/2 = 45 Thus, 45 is equal to its complement.
Can two angles be supplementary if both of them are acute.
No, because sum of two acute angles is less than 180.
Fill in the blank: If two adjacent angles are supplementary, they form a _________.

About NCERT Solutions for Class 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.
