Which of these is a valid argument concerning the measures of the corresponding angles of similar triangles?
a.
Similar triangles must have the same shape, so the measures of the corresponding angles must be equal to each other.
b.
Similar triangles do not have to have the same shape, so the measures of the corresponding angles do not have to be equal to each other.
c.
Similar triangles must be the same size, so the measures of the corresponding angles must be equal to each other.
d.
Similar triangles do not have to be the same size, so the measures of the corresponding angles do not have to be equal to each other.
