Question

Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5), C'(-2,-2) triangle are congruent when reflected over the x-axis.

Answer 1

If we reflect a point on a coordinate plane over x-axis the number of y- axis will be multiplied by -1
