Answer:
If two angles are supplementary, then they must form a straight angle. If two angles are obtuse, then they can be vertical angles. If two angles are vertical angles, then they will always be congruent.
Step-by-step explanation:
If two angles are obtuse, they must be congruent. It is false.
An angle that is greater than 90° but less than 180° is called an obtuse angle.
We can say two angles are congruent if the values of those two angles are same along with their corresponding sides. It is also true that, when two angles are proven to be congruent, then they will coincide when they are superimposed.
If two angles are obtuse, they might not be congruent. If we take any two angles as an example such as 100° and 160°. These two angles are obtuse as they both are greater than 90° and less than 180°.
However, they are not congruent as their value are different.
