Identify which of the following pairs of angles are complementary and which are supplementary: (iv) Are $$\angle BOD$$ and $$\angle DOA$$supplementary? If $$\angle 1$$ is decreased by some degrees, then $$\angle 2$$ will also be increased with the same degree, so both the angles will remain supplementary. When two angles are supplementary, each angle is said to be the supplement of the other. 7. Solution: Lines and Angles Exercise 14B – Selina Concise Mathematics Class 7 ICSE Solutions.

According to this model, the result is equal to $$\angle 1 + \angle 2\,\, \gt 45 ^\circ + \angle 2.$$ Now, it’s a matter of finding Is its complementary angle greater than $$45^\circ$$ or equal to $$45^\circ$$ or less than $$45^\circ.$$, Let there be two angles $$\angle 1$$ and $$\angle 2 .$$, Therefore$$\angle 1 \gt 45^\circ$$ (given), Adding $$\angle 2$$  to both sides ,we get, $$=\gt \angle 1 + \angle 2 \gt 45^\circ + \angle 2\\ =\gt 90^\circ \gt 45^\circ + \angle 2 \\ =\gt 90^\circ - 45^\circ \gt \angle 2 \\ =\gt 45^\circ \gt \angle 2$$, Therefore, its complementary angle will be less than $$45^\circ.$$, (i) Is $$\angle 1$$ adjacent to $$\angle 2$$ $$?$$, (ii) Is $$\angle AOC$$ adjacent to $$\angle AOE \,?$$. If ∠1 is decreased, what changes should take place in ∠2 so that both the angles still remain supplementary? Make the best use of these solutions to solve the exercise problems. Identity each of the given pair of angles as alternate interior angles, co-interior angles or corresponding angles or none of these in the given figure: (i) ∠2, ∠6 (ii) ∠1, ∠6 (iii) ∠3, ∠5 (iv) ∠2, ∠7 (v) […] Class 7 Maths NCERT Solutions Chapter 5 Lines and Angles InText Questions Try These (Page 94) Question 1.
