Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

Step-by-step explanation:

Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.  

Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual

Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.

Step-by-step explanation:

Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
