Which pair of equations can be used to verify the rectangular form, z = a + bi, and the polar form of a complex number are equivalent? a = sin(θ) and b = cos(θ)
a = cos(θ) and b = sin(θ)
a = rsin(θ) and b = rcos(θ)
a = rcos(θ) and b = rsin(θ)

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
