Answer:
P'(7, 5)
Step-by-step explanation:
Rule for the transformation of a point defines,
Reflection of a point P(x, y) about a line, x = 1 which is parallel to y-axis.
Line x = 1 works like a mirror so the distance between the line and the image point will be equal to the distance between the line and the original point.
Distance between the line and a point (-1, 5) = 4
Therefore, distance between the line and the image point = 4
Coordinates of the image point will be,
P'(3, 5)
The Pythagorean theorem works.
Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)
Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)
