It is always true because two congruent angles that are complementary both measure 45 degrees.

Always: that's what makes a rhombus a rhombus. A+ Homies
Sometimes. Remember, in order for two polygons to be similar, their angles must be congruent, and their corresponding sides must be proportional. In a rhombus, it is always possible for the angles to differ.
Never
Sometimes they are, sometimes they are not.
Sometimes they are, sometimes not.
Congruent figures are always similar. However, similar figures are only sometimes congruent.
Yes. Thay may, or may not, be congruent.
They are sometime congruent because a square is a parallelogram and its sides are congruent and a rectangle is one and its sides aren't congruent.
"Congruent" means "same shape and size as the other one". So one thing all by itself is never congruent. It needs something else to be congruent with. An isosceles triangle is never congruent to a scalene triangle, sometimes congruent to any other kind of triangle, and always congruent to another isosceles triangle that's congruent to the first one.
