Question

If two lines intersect at a 90 degree angle, what can you say about the lines?

Answer 1

You can say that the lines are perpendicular :D

Answer 2

thank you! DO you know thus one : The rules of parallel and perpendicular lines are different in spherical geometry than in Euclidean geometry. true or false?

Answer 3

Its true

Answer 4

The image below shows two parallel lines cut by a transversal. What is the value of a?

Answer 5

What you are going to do is (2a +3)º + aº = 180º

Answer 6

thank you, & how to do this one?
If two parallel lines are cut by a transversal and two alternate exterior angles measure 5x + 3 and 2x + 21, what is the value of x?

Answer 7

So for 2a + 3 + a = 180 x=30??

Answer 8

It would be a = 59, and for the other one since there alternate exterior angles they are going to equal each other. So you would set it up like this: 5x + 3 = 2x+ 21

Answer 9

I have to go now but the answer is for the second one is x = 6, I will be on later to answer any other questions =D

Answer 10

thank you!!

Answer 11

I am back if you have anymore questions :D

Answer 12

The image below shows two parallel lines cut by a transversal. What is the value of x?
x = 70 right?

Answer 13

Yep, perfect!

Answer 14

okay, & how to solve this?
What is the value of x?

Answer 15

its means they are equal right? so it would be 2?

Answer 16

These are vertical angles, which means they equal each other. You would set up the problem like this: 12x - 7 = 4x + 9

Answer 17

Yep, thats correct

Answer 18

okay &
If lines are perpendicular, what do you know about the angles at which they intersect?

Answer 19

okay, so if we have two lines that are intersecting we know that all the angles will be = to 90º, or right angles

Answer 20

alright,The point where two rays meet to form an angle is called what?

Answer 21

The vertex

Answer 22

What is the value of x?

Answer 23

What is the question?

Answer 24

what is the value of x?

Answer 25

also whats the value of x for this one 2? How do you find the value. I dont get how too?

Answer 26

It is going to equal 4, for the first one, so it'll be set up like this: -3x+1=4, and for the second problem it'll be 4x-2=6. We get this because there are 6 spaces in between the two lines, does that make sense?

Answer 27

oh okay i get it thanks. Is a segment bisector makes two segments that have equal length. true or false?

Answer 28

True

Answer 29

Last question :
Which of the following is not a correct name for this line?

Answer 30

what are the following options?

Answer 31

sorry my bad they are:

Answer 32

This either BC or C, I am not sure which one

Answer 33

alright thank you!(:

Answer 34

No problem, if you ever have anymore question you can send them to me
