ABC is a right angled triangle with angle B = 90 ^@ , a=6 cm if the radius of the circumcircle is 5 cm then the area of Delta ABC is

In a right angled triangle ABC, median BD divides right angle in 2 : 1 find the area of Delta if BD = 10 cm angle B = 90^(@)

In a right triangle ABC, angle B = 90^@ : If AB = 6 cm, BC = 8 cm, find AC

In the figure, given below, PQR is a right angled triangle right angled at Q. XY is parallel to QR, PQ = 6 cm, PY = 4 cm and PX : XQ = 1:2. Calculate the lengths of PR and QR.
