Find the length XZ in the triangle above.

In the figure above, PQRS is a circle with ST//RQ. Find the value of x PT = PS.

In the diagram above, find the ratio |PQ|/|PR|

If the hypotenuse of a right-angle isosceles triangle is 2, what is the length of each of the other side?

In the diagram, ∠PMN = ∠PRQ and ∠PNM = ∠PQR. If /Pm/ = 3cm, /MQ/ = 7cm and /PN/ = 5cm, find /NR/
