can you please post one question at a time? which question do you need help with? Angle XYZ is formed by segments XY and YZ on the coordinate grid: A coordinate plane is shown. Angle XYZ has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. Angle XYZ is rotated 270 degrees counterclockwise about the origin to form angle X′Y′Z′. Which statement shows the measure of angle X′Y′Z′? m∠X′Y′Z′ = m∠XYZ m∠X′Y′Z′ = 180 degrees m∠X′Y′Z′ = 270 degrees m∠X′Y′Z′ = 2 × m∠XYZ

can you add a picture of the coordinate plane?

ah ok, so do you have an idea of what the answer might be?

carmelle · Answer

ok... this question is pretty straight forward and cant tell you a direct answer. But what I will say is that when an angle is rotated, the size, shape, or measurement does not change. Since you know that, you should be able to eliminate a few answer choices.

so do you understand? based on what I said, which choices can you eliminate?

what do you not understand so that I can explain it better?

ok, if you rotate a angle will the angle stay the same measurement? yes or no?

carmelle · Answer

are you sure? look at an example, I will attach a photo.

in the picture, the triangle was rotated. does the triangle stay the same shape and size?

carmelle · Answer

the size stayed the same... and so did the shape..

carmelle · Answer

ok so, the same thing can be applied for triangle XYZ and X'Y'Z'.

which of the choices say that the two triangles are equal?

carmelle · Answer

what?

how did you get that?

those two answers would be `wrong` since triangle XYZ was never equal to 180º or 270º

carmelle · Answer

why are you giving two answer choices? isnt there supposed to be only one?

carmelle · Answer

yea but im asking which of the answers would be correct based off of the explanation I gave...

we already eliminated two of them...

carmelle · Answer

yes great job! that would be the correct answer :D
do you understand why it is correct?

Zari · Answer

carmelle · Answer

ok, just remember when you rotate an angle, the size and shape `DO NOT CHANGE`
