In sinilar cones are the angles that makes the sector equal or in proportion?

Answer 1

Always remember that in geometry and in case of SIMILARITY the angles are ALWAYS EQUAL.....

Sides are ALWAYS in PROPORTION (It can be 1:1 proportion also , meaning sides are equal, but it is not necessary in every case)

Be it a 2-D, 3-D, Plane, Solid, Polygon whatever....

If angles are not equal then the things which you want to compare can NEVER BE similar.

So in your case the angles are EQUAL

Answer 2

The angles would be equal in similar cones. The lengths can be in proportion but the angles have to be the same.

Answer 3

i would say equal
