The sum of the angles in the triangle is 180°.

The three angles are adjacent and form a straight

The third angle is 45°.

There is a pair of congruent angles.

Step-by-step explanation:

The diagram is missing but we can dwell on the limited information to answer.

We know angles in a triangle add up to 180°.

Therefore when we cut all these angles and arranged them on a straight line, their sum should be 180°.

Since the three angles are on a straight line they are adjacent.

Since the diagram is missing, these are the truth statement we have for now.
