HELP PLEASE WILL MEDAL AND FAN
Identify the image of triangle XYZ for a composition of two 90 degree rotations about point X

Answer 1

I think it's C

Answer 2

If you rotate an object 90 degrees TWICE about a point, how many total degrees has the object rotated?

Answer 3

180 degrees

Answer 4

So what do you already know about "180 degrees"?

Answer 5

What do you mean? Like, where would the each angle be after rotation?

Answer 6

FROM GEOMETRY, if you say that the angle created from rotating an object is 180 degrees, what is created as a result?

Answer 7

Well, I know it's called a reflex angle?

Answer 8

How about a straight line? The measure of the angle created by a straight line is 180 degrees, right?

Answer 9

Oh yes, sorry

Answer 10

Okay, so now, looking back at the answer choices, which one of the choices represents a straight line created as a result of rotating the object 180 degrees?

Answer 11

A?

Answer 12

you're guessing. The straight line that is created goes through the point the object is being rotated about.

Answer 13

Okay, it's being rotated about point X. And answer b is showing that if I'm not mistaken

Answer 14

Correct.

Answer 15

Okay, so my answer is B?

Answer 16

Yes

Answer 17

Thank you
