No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
always
Angles aren't congruent. Equal angles do not add up to 90 degrees unless they are 45 degrees. Complementary angles, by definition, add up to 90 degrees.
If 2 angles are congruent and complementary, they must each be 45 degrees.
No. The only requirement for a triangle to be a 45-45-90 triangle is for it to have at least two congruent sides/angles. The measure of the two congruent angles can be anything.
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
Complimentary angles ARE NOT always congruent. However, if one angle is 45 degrees, then they would be congruent since the other would have to be 45 degrees to add up to 90 degrees.

Nope one angle can be 45 degrees while the other one can be 55 degrees
It is always true because two congruent angles that are complementary both measure 45 degrees.
If 2 angles are congruent and complementary, they must each be 45 degrees.
Complementary angles add up to 90 degrees. If congruent then: 45+45=90
No because an isosceles triangle has various two congruent angles. A 45-45-90 triangle is technically an isosceles triangle.

If they are congruent, they have the same measure. If they are complementary, their sum is 90 degrees. So each one of them must be a half of 90 degrees. That is, 45 degrees each.
Vertical angles must be congruent so if they are complementary, they must be 45 degrees to be complementary.
