Explanation:

• For $\overline{AB}$: It represents segment $AB$, so the answer is C.
• For $\overleftrightarrow{AB}$: It represents line $AB$, so the answer is M.
• For $\overrightarrow{AB}$: It represents ray $AB$, so the answer is Y.
• For $AB$: It represents the length of segment $AB$, so the answer is B.
• For $\angle ABC$: It represents angle $ABC$, so the answer is A.
• For $m\angle ABC$: It represents the measure of angle $ABC$, so the answer is L.
• For $^{\circ}$: It represents degree, so the answer is S.
• For $

eq$: It represents is not equal to, so the answer is A.

• For $\perp$: It represents is perpendicular to, so the answer is R.
• For $\parallel$: It represents is parallel to, so the answer is E.
• For $\triangle ABC$: It represents triangle $ABC$, so the answer is P.
• For $\pi$: It is just $\pi$ (the mathematical constant), so the answer is A (assuming it's a typo and they mean the symbol itself, but if we consider the options, maybe it's a wrong - labeled option. But based on the given options, if we assume it's about the symbol $\pi$ as is, and there is no exact match, but if we consider the option A as a wrong - labeled one for $\pi$ (since other options don't fit), we can say A).
• For $\approx$: It represents is approximately equal to, so the answer is U.
• For $=$: It represents is equal to, so the answer is O.
• For $\cong$: It represents is congruent to, so the answer is R.
• For $<$: It represents is less than, so the answer is F.
• For $>$: It represents is greater than, so the answer is A.
• For $\geq$: It represents is greater than or equal to, so the answer is D.
• For $\leq$: It represents is less than or equal to, so the answer is R (assuming it's a wrong - labeled option. If we consider the options, there is no exact match for $\leq$ as "is less than or equal to" in the given options. But if we assume the option R is mislabeled (since other options don't fit), we can say R).
• For $\approx$ (again, if there is a duplicate symbol, same as above U).
• For $\cap$: It represents intersection, so the answer is B.
• For $\cup$: It represents union, so the answer is T.

Answer:

• $\overline{AB}$: C
• $\overleftrightarrow{AB}$: M
• $\overrightarrow{AB}$: Y
• $AB$: B
• $\angle ABC$: A
• $m\angle ABC$: L
• $^{\circ}$: S
• $

eq$: A

• $\perp$: R
• $\parallel$: E
• $\triangle ABC$: P
• $\pi$: A
• $\approx$: U
• $=$: O
• $\cong$: R
• $<$: F
• $>$: A
• $\geq$: D
• $\leq$: R
• $\approx$ (duplicate): U
• $\cap$: B
• $\cup$: T
