Question

Read the above and answer​

Answer 1

Answer:

Linear pair ∠1 &∠2,  Vertical angles ∠2&∠4, Supplementary angles ∠3&∠4,

Step-by-step explanation:

Taking n as transversal  on line l and m

linear pairs angles are supplementary angles that form a straight line (180 degrees)

∠1 &∠2,        ∠3&∠4,            ∠5&∠6,          ∠7&∠8

Vertical angles are opposite angles. they are congruent

∠2&∠4,       ∠1&∠3,           ∠6&∠8,            ∠5 &∠7

Supplementary angles are angles that form a straight line that is sum up to 180 degrees

∠1 &∠2,     ∠3&∠4,         ∠5&∠6,             ∠7&∠8

Answer 2

Answer:

geometry?

Step-by-step explanation:

vertical angles <1 & <3

linear pair : <1 & <2

supplementary: <1 & <2
