1.Which could be the name of a point?

A. EF
B. k
C. Q
D. MN

The possible name of a point could be any of the options given: EF, k, Q, or MN.

To determine which of the given options could be the name of a point, we need to understand what constitutes a valid point name.

In geometry, a point is denoted by a single uppercase letter. It does not contain any numerals or symbols (except for the letter itself). Additionally, it is common to use letters from towards the beginning of the alphabet (e.g., A, B, C) as point names.

Now let's apply these rules to the given options:

A. EF: This option consists of two letters (E and F), which, as per convention, would not usually be used together as a single point name. Therefore, EF is not a likely name for a point.

B. k: This option consists of a single letter (k), which follows the criteria of being a valid point name. Therefore, k could be a name for a point.

C. Q: This option also consists of a single letter (Q), which meets the criteria for a valid point name. Hence, Q could be a name for a point.

D. MN: Similar to option A, this option consists of two letters (M and N) and would not typically be used together as a single point name. Thus, MN is not a likely name for a point.

In conclusion, the options that could be the name of a point are:

B. k
C. Q
