What is the difference between complement and supplement angles




















I found the tea perfectly complementary to the lemon shortbread cookies served after lunch. Here, again, complementary is an adjective describing the tea. Therefore, complementary is the correct word choice.

My second job provides supplementary income, but I enjoy it much more than my full-time work. Since we are only talking about income, one idea, supplementary is the correct word choice. In math, these words describe the relationship between angles. A complementary angle is one in which two angles are added together to reach a sum of 90 degrees.

However, a supplementary angle refers to two angles that, when added together, reach a sum of degrees source. A common supplementary angle is actually a straight line, while a common complementary angle is a right angle. While the angles do not have to be next to or adjacent to each other, they do need to equal the exact sum, either 90 degrees or degrees respectively, to be called either complementary or supplementary. There are a lot of different ways these two unique, yet similar words are used in English.

In grammar, a subject complement refers to a word or phrase that follows a linking verb — such as is, will, or am — and describes the subject more completely. It can also identify an object with more specificity. I am a mom. The ice cream is vanilla.

There are quite a few common food or drink combinations that complement one another, such as fruit and cheese, chocolate and mint, coffee and donuts, and peanut butter and jelly. And in genetics, a gene that is considered complementary interacts with another gene in order to create a new, unique trait or characteristic source.

The latter refers, this time, to genes that work together to contribute to a single characteristic. Food vs. Bravo vs. Brava: What Is The Difference? The Basic Difference between Complement and Supplement Quite a few words in English can act as different parts of speech — a slight shift in spelling makes a noun an adjective or a verb a noun. This time, the word supplement is an action word. Let's look at a specific example where you might be asked to identify supplementary angles and complementary angles.

Here we have five angles; 1, 2, 3, 4 and 5 and we're told that this angle 3 is 90 degrees, now one thing that you can assume is that 1, 2 and 3 are all linear, so if you add up 1, 2 and 3 it would be degrees, which means that 1 and 2 must also sum to 90 degrees so I could label this as a right-angle. So complementary angles could be angles 1 and 2. So I could say angle 1 and angle 2. Now, a supplementary pair could be angle 4 and angle 5 which are adjacent and they are linear.

So notice that for a supplementary and for complementary you can't say that five angles are complementary but we're always talking about pairs or two's. So remember that when you're trying to evaluate your problems that supplementary sum to degrees or they're linear and complementary angles sum to 90 degrees.

Brian McCall. Thank you for watching the video. Connect and share knowledge within a single location that is structured and easy to search. On a site similar to this one I answered a question and the OP made a comment which prompted me to complete my answer in an edit. I called it "an example" but I originally wanted to call it "supplement" or "complement". So, I wonder: is either of these titles correct in this context?

Both with a different nuance of meaning? Complement refers to an item that completes or goes well with another item. Personally, I'd be inclined to refer to an 'example' edit as a supplement to your original post. If the addition of an example makes your answer more complete though, you could certainly refer to it as a complement. AJ01 correctly defines the different meanings of the two words, but I think the main difference between them is that you shouldn't use complement at all unless you're very sure why you want it.

Complement is quite rare outside specialised contexts music, geometry, computing, etc. It doesn't really mean "goes together well with" - people just assume that because one of the few 'correct' common usages is, say, Mint sauce complements roast lamb. Where it means "makes complete", not just "is good with".

If only to avoid confusion with the totally unconnected compliment , I suggest you steer clear of this word. Supplement is perfectly valid for your example. I'm not sure I'd use either in this case but complement would be my first choice of the two given the context that what you provided was a completion. To be honest though, given the nature of sites like this, maybe I'd go for addendum.

Reason being that I find requests on such sites to be like technical specifications, inasmuch as neither are often frozen in their requirements - 'completion' becomes a rarity, and additions seemingly perpetual. A Complement usually makes the word that it goes with complete or perfect. A Supplement, however, only helps that word. It is purely supplementary. Therefore it depends how you would like to make yourself mean. In your question, either word would have been correct.
