It is always true because two congruent angles that are complementary both measure 45 degrees.
The statement is false.
angle B and angle D are supplements, angle B is congruent to angle D, angle A is congruent to angle A, or angle A is congruent to angle C
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.

definition of congruent angles
Two figures are congruent if and only if they have the same shape and size.

True. -------------------------------------------------------------------- Two angles which are complementary have a sum which is 90° If the two angles are congruent, they are each half of 90° = ½ × 90° = 45° →The statement is true.
I'm not able to view the statement or context. However, if you provide it to me, I can help you determine the technique being illustrated.
A real number is any number. Real numbers can be whole numbers or numbers which include a decimal point.
That may vary. The only requirement for being called "isosceles triangle" is that two of the angles are congruent. (This is equivalent to the statement that two of the sides are congruent.)That may vary. The only requirement for being called "isosceles triangle" is that two of the angles are congruent.

The proof would finish with the statement:"Therefore, bc is congruent to de".
