Step-by-step explanation:
i think thats right, sorry if its not
Answer:
A and D are 87 degrees
C is 28 degrees
and B is 65 degrees
Step-by-step explanation:
28 degrees and c are congruent
a and d are congruent
65 degrees and b are cungruent
B(65)+28+D= 180
65+28= 93
93+D=180
D=87
A=D(87)
No
For future reference: When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
