Which angle pairs are supplementary? check all that apply. ∠1 and ∠2 ∠4 and ∠3 ∠4 and ∠5 ∠7 and ∠5 ∠3 and ∠6

The pairs of angles that are supplementary are:

∠4 and ∠3

∠4 and ∠5

∠3 and ∠6

Supplementary angles are those angles that can be summed up to 180° when added together.

From the attached diagram,

angles(<) 3, 4, 5, and 6 makes up an angle of a point =  360°

when divided  360° ÷ 2

                      = 180°

Therefore, two angles at that point formed by <3,4,5 and 6 is a total of 180°

T he pairs of angles that are supplementary are:

∠3 and ∠6

∠4 and ∠3

∠4 and ∠5

To solve this question, we need to know the meaning of supplementary angles.

By definition, 2 angles are said to be supplementary if they sum up to 180°

From the attached image in the question, we will find the angles that are supplementary to each other.

First of all, from trigonometry, we know that sum of angles on a straight line is 180° .
