Assemble the proof by dragging tiles to the statements hell

See explanation

Step-by-step explanation:

1. - given

2.   - definition of midpoint (the midpoint of the segment divides the segment into two congruent segments)

3. - corresponding angles theorem (corresponding angles theorem states: If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.)

4. - SAS (SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent).

the answer will be b x² +x-1
