Yes!
Because -10 - 5 is -15 and -10 + (-5) is also -15 so they’re equal!

Answer:

See below

Step-by-step explanation:

Given :-

y || z

To Prove :-

m∠5 + m∠2 + m∠6 = 180°

Proof :-

Here we are required to prove that ,

$\rm\implies m\angle 5 + m\angle 6 + m\angle 2 = 180^o$

And here it's given that , y || z . Therefore ,

∠3 = ∠6 ( alternate interior angles )
∠1 = ∠5 ( alternate interior angles )

Now we know that the measure of a straight line is 180°. Therefore ,

$\rm\implies m\angle 1 + m\angle 2 + m\angle 3 = 180^o \\\\\implies\boxed{\rm m\angle 5 + m\angle 6 + m\angle 2 = 180^o}$

From 1 and 2 .

Hence Proved !

Which of the following is a characteristic of the circumcenter of a triangle

jolli1 [7]

You have not provided the options, therefore, I can not provide an exact answer.

However, I will help you with the concept

In a triangle, the circumcenter is defined as the point of intersection of the three perpendicular bisectors in the triangle

The circumcenter is characterized by the following:

1- The circumcenter is the center point of the circumcircle

2- The circumcenter is equidistant from the three vertices of the triangle

3- Position of circumcenter:

in acute triangle ........> it lies inside the triangle

in right-angles triangle .......> it lies at the midpoint of the hypotenuse

in obtuse triangle ..........> it lies outside the triangle

Hope this helps :)
