Similar shapes need to have the same number of sides, the same angles and the ratio of the sides needs to be the same. Rectangles are not always similar to each other because they can have different dimensions, which would break the "same ratio" rule.

Are two hexagon always similar to each other?
No. Two regular hexagons are always similar to each other, but two random hexagons are not necessarily similar.
Which quadrilaterals are always similar to each other?
Parallelogram
Are two regular hexagons are sometimes always or new similar to each other?
always
Can you call a 4 sided shape a parallellogram?
Only if 2 sides are parallel with each other, and the other two sides are also parallel with each other. All squares are rectangles. All rectangles are parallelograms. All parallelograms are 4 sided. But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.
Are two circles sometimes always or never similar to each other?
They can b different sizes
Does rectangles always have perpendicular sides?
Yes the 4 corners of a rectangle are perpendicular to each other and its opposite sides are parallel to each other.
Are two hexagon always similar to each other?
No. Two regular hexagons are always similar to each other, but two random hexagons are not necessarily similar.
Which quadrilaterals are always similar to each other?
Parallelogram
How many sides are there on two rectangles?
Rectangles must always have 4 sides. As there are two rectangles, there must be 8 sides. However, if these two rectangles have identical sized sides and they are placed against each other so that they look like one rectangle, there will only be 4 sides.
Are two regular hexagons are sometimes always or new similar to each other?
always
Why aren't all rectangles similar to each other?
there are two reasons one is they could be different ways or they could be plastic shapes or a real thing
Do diagonals of a rectangle bisect each other?
The diagonals of a square (which always bisect each other) are the same length.
Do similar triangles always have congruent angles?
Yes, in similar triangles, the angles are always congruent, and the sides have the same proportions to each other.
Can you call a 4 sided shape a parallellogram?

But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.
Are Two isosceles triangles are sometimes always or never similar to each other?
Sometimes.
