Question

∠3 and ∠4 are _______.

supplementary angles
complementary angles
vertical angles
congruent

Answer 1

Supplementary, this is math

Answer 2

Answer : The
`\angle 3\text{ and }\angle 4` are, supplementary angles.

Explanation :

Supplementary angles : The two angles are supplementary angle in whcih the the sum of those two angle are
`180^o`

Complementary angles : The two angles are complementary angle in whcih the the sum of those two angle are
`90^o`

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,

`\angle 1\text{ and }\angle 2`,
`\angle 2\text{ and }\angle 3`,
`\angle 3\text{ and }\angle 4` and
`\angle 4\text{ and }\angle 1` are the supplementary angles.

`\angle 1\text{ and }\angle 3` and
`\angle 2\text{ and }\angle 4` are the vertical angles.

Hence, the
`\angle 3\text{ and }\angle 4` are, supplementary angles.
