It all started when a friend of mine was arguing with our math teacher. So I approached them and started asking the teacher, what's going on? While holding an exam excerpt he said "Look at this question." What was actually a question in which you should find out the area of the triangle. So after looking at the question I asked the teacher "what is it with this question?" He said your friend didn't solve it and we did train on this question precisely plenty of times last night. So I asked my friend "Why didn't you solve it?" He replied because the triangle we trained upon last night was named (A B C) and the one in the exam is named (X Y Z).
