George said that in a triangle, the sum of all angles is the same as the sum of opposite angles of a cyclic quadrilateral.
Fred said that if in a right angled triangle, a perpendicular is dropped from the right angled corner to the hypotenuse of the triangle and the sines of both the angles multiplied by their respective distances from the right angled corners is the same then the triangle is always an Isoscales one also.
Who is wrong?

If you have an Acute triangle of sides a, b, c and angles A, B, C respectively. If you double the side a, triple the side b, and keepthe side c constant, also if you change the angles so that A bocomes A+ 45, and B becomes B+60. What will be total change in figure?
It wont remain a tringle anymore
It will become an isosceles triangle
I will become an obtuse triangle
It will remain acute
