# Can you figure out my name?

I can be mad, I can be wrong,

Both my lines are equally long,

With out I cancel a mistake,

With up I fake,

I have a green opposite,

And a hollow opponent when you see me in a game,

Can you figure out my name?

CROSS

I can be mad, I can be wrong,

Cross can mean mad and the cross symbol (x) could signify that something is wrong.

Both my lines are equally long,

The cross symbol normally is made of two lines of equal size overlapping each other

With out I cancel a mistake,

Cross out means to cancel

With up I fake,

Cross up means to deceive someone.

I have a green opposite,

A green tick as in the checkmark!

And a hollow opponent when you see me in a game,

A nought ‘O’ in noughts and crosses.

Red Cross - as "I have a green opposite"
