ok here is the next one

jonahneedshelp2121:

this one looks harder

AZ:

Remember the previous question we just answered? They wanted us to prove that the triangles were similar by showing that there were two congruent (that means equal) angles

Phantomdex:

Alright my knowledge on this only goes so far so, I guess I'll be taught this as well now lol

jonahneedshelp2121:

ok

jonahneedshelp2121:

b and e are the same and f and c and the same angles right?

AZ:

This question is asking us to do the same exact thing. Angle A and D are equal to each other. (They're both 90 degree angles)

AZ:

Yes

ok

jonahneedshelp2121:

so know i know that what do I do next?

jonahneedshelp2121:

ok

AZ:

This question basically asks the opposite of what that question was asking

jonahneedshelp2121:

ohhh

jonahneedshelp2121:

hmmm

jonahneedshelp2121:

this part is confusing

jonahneedshelp2121:

∠E onto ∠B where ∠E is congruent to ∠B,

AZ:

Actually I was mistaken

AZ:

This just means that they rotated the triangle so now it looks like this |dw:1637168587708:dw|

jonahneedshelp2121:

oh ok

jonahneedshelp2121:

so what is my next step?

AZ:

The drawings aren't to scale Because the question states rigid transformations which are translation, rotation, and reflection. This doesn't change the shape, it just moves it around

jonahneedshelp2121:

oh

jonahneedshelp2121:

i kind of like the D opjtion

AZ:

That is correct

jonahneedshelp2121:

segment DE ~ segment AB because of the definition of similarity in terms of similarity transformations

jonahneedshelp2121:

but that was kind of a guess to be truthful

AZ:

It can't be answer choice A because it doesn't match the angles correctly triangle ABC would be similar to triangle DEF while answer choices A and C both have it as ABC and FDE

AZ:

Actually I think it should be B The series of rigid transformations got triangle DEF to overlap on triangle ABC but they are similar triangles, not congruent triangles

jonahneedshelp2121:

ohhh

jonahneedshelp2121:

how?

AZ:

If you rotate the triangle DEF, you'll get it to look just like triangle ABC

jonahneedshelp2121:

oh ok that makes more sence

AZ:

We already know that angle A and D are equal. And we are told that angle E and B are congruent in the question

jonahneedshelp2121:

also i have a BIG typing part that I 100% need help to understand

jonahneedshelp2121:

you there?

Phantomdex:

I think they went offline

jonahneedshelp2121:

oof

Phantomdex:

Oof indeed

can you help me on 1?

Phantomdex:

Um, I'll be honest I'm not sure I'll even now what's going on in the question

jonahneedshelp2121:

ok what to see what i looks like?

I tried to send a message to you.. i need help with 1 last one

Phantomdex:

Oh, um-

Phantomdex:

I don't know that one sorry

jonahneedshelp2121:

np

jonahneedshelp2121:

ok everyone i am making a new one
