the reference angle for 5pi/4 is pi/4, which has a terminal point of (sqrt2/2,sqrt2/2). What is the terminal point of 5pi/4?

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.
