Triangle abc is transformed to triangle a′b′c′, as shown below: which equation shows the correct relationship between the measures of the angles of the two triangles? a. m< cab = m< c'b'a'b. m< bca = m< a'b'c'c. m< cab = m< c'a'b'd. m< bca = m< c'a'b'

After reflection, the shape still has the same size, area, angles and line lengths. So, if ΔABC is reflected about the x-axis to form ΔA'B'C' the corresponding angles have equal measures:

m∠ABC=m∠A'B'C',
m∠ACB=m∠A'C'B',
m∠CAB=m∠C'A'B'.
correct choice is C.
