Question

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'

Answer 1

did u get this question from flvs?

Answer 2

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'.
Answer: correct choice is C.
