i missed about 2 days of school and my teacher only uses videos to teach and in class is like the extension of those videos and homework time

do you know about verticl angles

patent violet Jan 20, 2025, 8:25 PM

#

rain parcel do you know about verticl angles

i watched a short video that my teacher gave and here are the notes

#

i know about the angles, I just dont know how to go about setting it up

#

this is what I tried

rain parcel Jan 20, 2025, 8:27 PM

#

patent violet this is what I tried

no.

patent violet Jan 20, 2025, 8:27 PM

#

i know this is probably easy stuff ive just always been slow in math 😭🙏

#

i had to study a lot for algebra

rain parcel Jan 20, 2025, 8:27 PM

#

patent violet i know about the angles, I just dont know how to go about setting it up

these are transversal laws.

#

hmm, let me illustrate it.

patent violet Jan 20, 2025, 8:28 PM

#

okay

rain parcel Jan 20, 2025, 8:29 PM

#

what would the measure of the question mark angle be, in terms of a?

It feels like maybe they need a bit more hands-on teaching than that.

@patent violet So this image displays the angles alpha, beta, gamma, and delta. Now, given this image, what can we say about alpha and beta? Like, without knowing anything else about them other than what's in the image?

they add up to 180?

obsidian nebula Jan 20, 2025, 8:32 PM

#

patent violet they add up to 180?

Right, because they add up to the line, and the line is 180.

patent violet Jan 20, 2025, 8:32 PM

#

yes

obsidian nebula Jan 20, 2025, 8:32 PM

#

Now, what can we say about beta and gamma?

patent violet Jan 20, 2025, 8:32 PM

#

they also add up to 180

obsidian nebula Jan 20, 2025, 8:32 PM

#

Right.

#

So we have alpha + beta = 180 and beta + gamma = 180.

#

Which means, by the transitive property of equality, that alpha + beta = beta + gamma, right?

patent violet Jan 20, 2025, 8:33 PM

#

yes

obsidian nebula Jan 20, 2025, 8:33 PM

#

Therefore what can we say about alpha?

patent violet Jan 20, 2025, 8:33 PM

#

alpha = gamma

obsidian nebula Jan 20, 2025, 8:33 PM

#

Right.

#

And that's the theorem. Opposite angles are congruent.

#

Their measures are equal.

patent violet Jan 20, 2025, 8:34 PM

#

ohh okay

#

i couldnt see that because idk on the diagram or however you call it alpha looks smaller than gamma

#

so i thought alpha would be smaller than gamma by how it looks if that makes sense?

obsidian nebula Jan 20, 2025, 8:34 PM

#

I literally drew them as two intersecting lines with a straightedge.

patent violet Jan 20, 2025, 8:35 PM

#

obsidian nebula I literally drew them as two intersecting lines with a straightedge.

i mean how wide they are

#

#

that doesnt mean congruent

obsidian nebula Jan 20, 2025, 8:35 PM

#

...that's alpha and beta.

patent violet Jan 20, 2025, 8:35 PM

#

wait

#

omg

#

nvm then im

obsidian nebula Jan 20, 2025, 8:35 PM

#

No, those little arcs just mean we're considering the angles.

patent violet Jan 20, 2025, 8:36 PM

#

okay okay

#

i already knew alpha and gamma were equal

#

x + 11 = 5x -33

#

im talking about how do you find the variable because

#

i did that

#

i solved that

#

and i got something that is not a whole number

#

but it is requiring a whole number

obsidian nebula Jan 20, 2025, 8:37 PM

#

You probably just made a mistake in your working. Can you show it?

...how is 11 not a whole number?

patent violet Jan 20, 2025, 8:38 PM

wait nvm

#

whoops

#

i plugged it into

#

I plugged it back in

#

im an idiot sorry

obsidian nebula Jan 20, 2025, 8:38 PM

#

...that would also give you a whole number unless you did it wrong.

patent violet Jan 20, 2025, 8:38 PM

#

i was so convinced i was wrong

#

i overlooked it

#

IM SO SORRY

obsidian nebula Jan 20, 2025, 8:39 PM

#

It's okay, we all make mistakes.

#

That's why we show our work.

patent violet Jan 20, 2025, 8:39 PM

#

no but that is SUCH A STUPID MISTAKE

#

i am so sorry for wasting your time

obsidian nebula Jan 20, 2025, 8:39 PM

#

Dude, chill. You just need an outside perspective sometimes.

#

Maybe you should take a short break before you do any more.

#

You seem pretty worn out.

patent violet Jan 20, 2025, 8:40 PM

#

probably 😭🙏 this is the 3rd homework ive done in a row

#

and the other 2 i spent like 10 minutes just staring confused

#

i will take a break thank you
