A number of computer programs and phone apps have built in spell-checkers. If the word you have used is not one which the computer/phone recognizes, it marks it with a squiggly red line. This does not necessarily mean that you have spelled the word wrong: it could be a proper noun, or a slang word, or a spelling which is not used by the geek who created the program. The squiggly line is only an alert; you must decide if the word actually needs changing.
The word is mispelledA RED squiggly line means the word is misspelled. A GREEN squiggly line means that there is one or more extra space or tab characters that aren't grammatically needed.

It means congruent. It is NOT 'approximately equal', which would be an equal sigh where BOTH lines are squiggly.
The squiggly line in music notation is called a trill. It indicates that the musician should rapidly alternate between the written note and the note above it.
If you mean the n with a squiggly line on top, it's pronounced en-yay.

You are most likely referring to a quarter rest, which means to stop playing for the time assigned to a quarter in the given time signature. If it is a really long squiggly line then you might be looking at a glissando, which basically means to glide from the top note to the bottom note indicated by the mark.
The "squiggly line" is called a break. It is used to show a break in the intervals on the y axis (x too). For example: if the numbering starts at 0, but the next number is 300, after you put 0, you an put a break, and then you can put 300.
It means to play all the notes between the two listed in the given time.
The 2 squiggly lines (~) is called a tilde. It can mean "approximately" or "similar to" in text, as well as indicate a range of values. It is also used in some languages as a diacritic mark to change the pronunciation of a letter.
it means that from zero to the first number next to the graph is not in the same order as the other numbers. for example it might me 0,10,15,20,25. there will be a squiggly line after 0 because 0+5 is not 10 and the pattern here is adding 5 each time. hope this helps:)
If by perentaces you mean parentheses (or brackets) and not percentages then it means your emergency brake is on. To fix it just pull the emergency brake release handle and the pedal should come back again.
