Answer : The [tex]\angle 3\text{ and }\angle 4[/tex] are, supplementary angles.
Explanation :
Supplementary angles : The two angles are supplementary angle in whcih the the sum of those two angle are [tex]180^o[/tex]
Complementary angles : The two angles are complementary angle in whcih the the sum of those two angle are [tex]90^o[/tex]
Vertical angles : Vertical angles are the angles that are opposite to each other when two lines intersect each other.
Congruent angle : It is defined as they have the same angles.
From the above information we conclude that,
[tex]\angle 1\text{ and }\angle 2[/tex], [tex]\angle 2\text{ and }\angle 3[/tex], [tex]\angle 3\text{ and }\angle 4[/tex] and [tex]\angle 4\text{ and }\angle 1[/tex] are the supplementary angles.
[tex]\angle 1\text{ and }\angle 3[/tex] and [tex]\angle 2\text{ and }\angle 4[/tex] are the vertical angles.
Hence, the [tex]\angle 3\text{ and }\angle 4[/tex] are, supplementary angles.
