Answer:

The correct option is;

c.

Step-by-step explanation:

The given translation given is that of a reflection across a line ST

Whereby we take the line ST to represent the x-axis, then a reflection across ST will be of the form;

Coordinates of point of primage before reflection = (x, y)

Coordinates of point of image after reflection = (x, -y)

Therefore, the coordinates of the point of the reflected image of U will be the same as the coordinate of the point J and the image of U coincides with the point J

Therefore, the image of U and J are the same distance along the same ray from the T.

When a triangle is reflected, it must be reflected across a line.

The true statement about the reflection is (b) the image of U and J are the same distance along the same ray from T

From the question, we understand that:

Triangle STU is reflected across line ST

This means that, triangle STU will be flipped over line ST, such that point U and point J will coincide

This is so because, the distance from point J to line ST is the same as the distance from point U to line ST

Hence, the valid reason is (b)
