Triangle ABC in quadrant one with angle A measuring 63 degrees, triangle A prime B prime C prime in quadrant one to the right and above triangle ABC Triangle ABC has been translated to create triangle A′B′C′. Which of the following statements is true? A) m∠B′ = 63°
B) m∠C = 63°
C) m∠A′ = 63°
D) m∠B = 63°

C) m∠A′ = 63°

Step-by-step explanation:

This is the answer because, is the exact shape because, of A prime and B prime and C prime so therefore, A must be the same exact same thing as A prime so therefore your answer would be m∠A′ = 63°.

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
