I really am confused on how to write a proof.

Since ABCD is a parallelogram, the opposite sides will be parallel and equal,

$\begin{gathered} AB=CD \\ BC=AD \end{gathered}$

Consider that AC acts as a transversal to the parallel lines AB and CD, so we can write,

$\begin{gathered} \angle CAD=\angle ACB\text{ (Alternate Interior Angles)} \\ BC=AD\text{ (Opposite sides of parallelogram)} \\ \angle ADB=\angle CBD\text{ (Alternate Interior Angles)} \end{gathered}$

So by the ASA criteria, the triangle AED is congruent to the triangle CEB,

Then the corresponding parts of the triangles will be equal,

$\begin{gathered} AE=CE \\ BE=DE \end{gathered}$

Hence Proved.

Answer:

"If Kendrick is excited, then music class is next."

Step-by-step explanation:

The conditional would be "not." If it is not, he is not. "If music class is next, then Kendrick is exited" could be correct if the grammar was too. You do not know if music class is next so they couldn't be excited. However, if he is excited, then music class has to be next.
