A)
FCE and CAB are congruent angles they are formed by the same line FA and two parallel lines between them
FEC and EDB are congruent angles for the same reason
B)we will write the measure of each angle based on the statement
The line AD contains the angles ABC,CBE and EBD if we sum all angles we make the line and the measure of a line is 180 degrees so
[tex]\begin{gathered} \text{ABC}+\text{CBE}+\text{EBD}=180 \\ 63+\text{CBE}+45=180 \\ \text{CBE}=180-63-45 \\ \text{CBE}=72 \end{gathered}[/tex]the CBE is 72°
C)
congruent triangles are those that have all their angles equal,Since all the triangles are copies of triangle ABC, they are all congruent since they all measure the same but are located in different ways
so a triangle congruent to triangle CBE can be any for example :ABC,BED or FCE
