Drag and drop a reason to each box to complete the proof ?

1. Vertical angles are congruent: a) we're proving that two angles are congruent (we use ≅), and it just happens that those two angles are vertical (opposite angles on two intersecting lines).

2. SAS congruence: It is one of the last three, since we're trying to prove the triangles' congruence, and it is SAS, because our given gives us two pairs of congruent lines, and we find that the angle between them are congruent.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
