Triangle ABC is reflected across the x-axis, and then across the y-axis. Which rotation is equivalent to this composition of transformations? A) 45 degree rotation B) 90 degree rotation C) 180 degree rotation D) 360 degree rotation

OpenStudy (stbest):

what do you think lets do the process of elimination 45 degrees will make the triangle sideways 90 will make it a little more than sideways 180 will make it half way turned 360 will turn it so much that it will be in the same position

OpenStudy (kalijah13):

so C)??

OpenStudy (stbest):

yes

OpenStudy (katiebuugcx):

C is correct. You can also think as if you had a line going through each corner closest to the vertex and the vertex itself and then see what angle is present where they meet :)

Thank you @Stbest and @KatieBuugCx
