How do i tell if an angle is supplementary or complementary?

Hello there!

It depends on what the angles add up to be. If they add up to be 90°, they are complementary. If they add up to be 180°, they are supplementary.

So, 90° = complementary

and 180° = supplementary

It's best to review it multiple times since it's easy to confuse them, or come up with your own little saying that'll work well depending on how you think you'd remember it best. For me, since 90° angles are also right angles, i just think: it is right to give some body a  complementary angle because complementary angle ... compliment get it? Anyways, not to confuse you, whatever works best for you! :) I hope I could help you today!

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
