The situation is shown in attachment.

the right angled frame of rods (in stationary ) is moving at speed v perpendicular to its hypotenuse.

according to length contraction the corresponding lengths of sides should contract.

So it may not remain a right angled triangle in moving frame.

but if 'V' is such that L*cos(90-a) contracts such that L contracts than half of hypotenuse (h/2) .

we know that hypotenuse can not contract .

Also both L(AB) & L(AC) contract less than h/2. what happens in that case?

(L is the length of each side, consider isosceles triangle.

∠a is the angle opposite to point A)
