Question

what classifications can you give to angle 3 and angle 4. (LIST ALL THAT ARE CORRECT)

Adjacent Angles
Linear Pair
Supplementary
Complementary

Answer 1

Adjacent means one side together. They have that.
Linear pair means they =180. That is true
Supplemental means they = 180. That is true
Complementary means they = 90. Thtanis not true

Answer 2

Answer: Second option is correct.

Step-by-step explanation:

As we know that

when a straight line is cut by a transversal or any other line.

It divides the straight line into two angles.

And the sum of two angles becomes supplementary.

And this pair of angle is known as "Linear pair".

So, ∠3 and ∠4 are linear pair and ∠3+∠4=180°.

Hence, Second option is correct.
