if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
The angle is 60°. Its supplement is 120°.
Only if the congruent angle is the angle between the two congruent sides (SAS postulate).
Subtract your angle from 180° and that's the supplement of your angle.
No, because they need not be congruent.
Yes, they are.
Supplementary Congruency Theorem
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
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
The transitive property is if angle A is congruent to angle B and angle B is congruent to angle C, then angle A is congruent to angle C.
HPE is an angle congruent to angle HRN.
TBP an angle congruent to angle PTB.
The angle is 60°. Its supplement is 120°.
The Symmetric Property of Congruence: If angle A is congruent to angle B, then angle B is congruent to angle A. If X is congruent to Y then Y is congruent to X.
A congruent angle can also mean equal angle. So there is no set measurement of a congruent angle. Just the same as the angle it is equal to.
Only if the congruent angle is the angle between the two congruent sides (SAS postulate).
If angle A is congruent to angle B, then angle B is congruent to angle A.If X is congruent to Y then Y is congruent to X.
