Is a night-angled triangle. PQ = 13cm. QR = 7cm and angle POR = 90°. Calcune
length of PR

can someone answer and explain

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.
