Geometry Level 5

Two circles intersect ω 1 {\omega}_{1} and ω 2 {\omega}_{2} each other at X , Y X, Y .

Straight line through A , B A, B is a common tangent to both the circles ω 1 {\omega}_{1} and ω 2 {\omega}_{2} .

A line through Y intersects ω 1 {\omega}_{1} and ω 2 {\omega}_{2} at C , D C, D , respectively.

A circle ω {\omega} passes through A , B , C , D A, B, C, D .

X Y = 47 , X D = 37 , X C = 67 XY = 47, XD = 37, XC = 67 . X C , X D XC, XD do not pass through centers.

Ignore the centre of circles.

Find value of A B 2 {AB}^2 .


The answer is 270.
