Question

In the diagram below, lines a and b are parallel and cut by a transversal, t. If angle 1 is 100 degrees, find the measure of angle 6.
Answers:


50

80

90

100

Answer 1

let me draw the digram

Answer 2

ok

Answer 3

Is it that same diagram as before?

Answer 4

yes

Answer 5

I'll snip and paste it over here. Just a sec.

Answer 6

ok

Answer 7

Here it is.

Answer 8

ok

Answer 9

We have to do this in two steps.
First, as in the previous problem, angles 1 and 2 form a straight angle.
So if angle 1 has measure 100, what is the measure of angle 2?

Answer 10

uhm...60..

Answer 11

100 + 60 do not sum to 180.

What is 180 - 100 --> This is the measure of angle 2

Try again.

Answer 12

oh so its 80

Answer 13

Right

Answer 14

If 2 parallel lines are cut by a transversal, corresponding angles are congruent.
Angles 2 and 6 are corresponding angles so they are congruent and have the same measure.
So, the measure of angle 6 = ? @kittymeow101

Answer 15

Angles 6 and 2 are congruent so they both have measure 80. Yes.

Answer 16

so the final answer is equal to 80

Answer 17

Correct.

Answer 18
