Identify which of the following pairs of angles are supplementary?
(i) 65°, 115°
(ii) 63°, 27°
(iii) 112°, 68°
(iv) 130°, 50°
Can two angles be supplementary if both of them are:
i) acute?
ii) obtuse?
iii) right?
If two adjacent angles are supplementary, they form a (a) .
If two lines intersect at a point, and if one pair of vertically opposite angles are acute angles, then the other pair of vertically opposite angles are (a) .
If two lines intersect at a point, then the vertically opposite angles are always (a) .
In the following figure, is ∠1 adjacent to ∠2?
No, ∠1 and∠2 are not adjacent angles
Yes, ∠1 and∠2 are not adjacent angles
Indicate which pairs of angles are:
(i) Vertically opposite angles
(ii) Linear pairs
i) Vertically opposite angles are ∠1 and ∠4, ∠5 and (∠2 + ∠3)
i) Vertically opposite angles are ∠5 and ∠1,∠4 and (∠2+∠3)
ii) Linear pairs are ∠1 and ∠5, ∠5 and ∠4
ii) Linear pairs are ∠1 and ∠3,∠1,∠4
