Question

if two angles are vertical then which of the following is not true

Answer 1

Is this the full question. Which following..?

Answer 2

the angles are congruent the angels share a common vertex the angles lie in the same plane the angles share a common side

Answer 3

Without drawing a picture .. this could get really confusing.
Here's the simplest way I can think of to say it.

To prove that any two angles are congruent, consider what vertical angles are. Vertical angles are two angles that share a common vertex that are formed by two lines (or line segments.) The simplest picture would be the letter X

X

the angle that is opening to the top we will call 1
the angle opening to the left we will call 2
the angle opening down we will call 3

<1 and <3 are vertical because they share the same point for a vertex and they are formed by the two straight line segments that make the letter X. If you can picture that -- then keep on reading! :-)


Look at X and the labels we just gave it .. <1 and <2 are supplementary (because together they equal 180°). We know this because <1 and <2 are a linear pair -- two angles that share a common side who's other sides form a straight line and who's angle measures total 180°.

<2 and <3 are supplementary because they also equal 180°.

The rules you just stated "supplements of the same angle are congruent" means that because <1 and <3 are both congruent to <2, then they are equal to each other.

This would be much, much easier to show you in person with a drawing and being able to point ... but, that just isn't going to happen, now is it...

Good luck -- and just remember proofs are not the easiest thing in the world. They just take practice.

Answer 4

you just instilled ultimate confusion upon me XO could you tell me the answer in short

Answer 5

One sec..

Answer 6

The angles lie in the same plane ....
