Which solid figure does not have any parallel faces?
Sphere
Does a sphere have parallel faces?
Since a "face" is usually defined as a flat area and no area of a sphere is flat, the answer would be NO. It is possible to place two planes tangent to the surface of the sphere and parallel to each other, but each plane will only touch the surface of the sphere at a single point rather than coinciding with a "face".
What has no equal angles no equal sides no parallel sides?
A circle or a sphere
What is a steradian?
A steradian is the solid angle subtended at the centre of a sphere by radius r by a portion of the surface of the sphere which has area r2.
Two parallel lines are coplanar?
Not necessarily. The Tropic of Cancer, and the Tropic of Capricorn, imaginary lines on the surface of the earth (an approximate sphere), are parallel but they are not coplanar. You could draw similar lnes on a proper sphere that were parallel but not coplanar.
What portion of the celestial sphere do you see at any time?
