Question

triangle abc is reflected over the line y=x . triangle abc has points a (10,2) , b (9,5) and c (6,4) . what is the c' coordinate?

Answer 1

The coordinates of C are 4,6 because thats the rule for y=x

Answer 2

C'=(4,6)

Explanation:

The reflexion of a point P with coordinates (x,y) over the line y=x is the point P' with coordinates (y,x). For example, the reflection point of a with coordinates (10,2) is a' with coordinates (2,10).

For this reason, the point c y reflect in C' with coordinates (4,6).
