Triangle $abc$ with vertices of $a(6,2)$, $b(2,5)$, and $c(2,2)$ is reflected over the x-axis to triangle $a'b'c'$. this triangle is reflected over the y-axis to triangle $a''b''c''$. what are the coordinates of point $c''$

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
