Prove these two triangles are contiguous

[warm wigeon]

4 marks I get it's SAS and i know why the angle is proof but how do I phrase the sides?

also its a right angled triangle with squares

i rlly need help so i appreciate it 🙏 i have a test tmr

You apparently know the angle so I won't touch on that, but it's there anyway
I labelled the sides that are congruent for each triangle (obviously the sides with the same colour are congruent). As its a square as you say, you know that they are the same size

I'm struggling to put it into an answer, like how could I word it so i get 4/4?

i saw some approaches that do it as side 1, then angle, then side 2 but i'm not sure how to implement that into the answer

[fringe mantle]

are the squares the same?

[warm wigeon]

i think so

[elder kelp]

Honestly it doesn't matter whether the squares are the same or not, it'd still be congruent in this case

[fringe mantle]

true say

[elder kelp]

You can rotate it and translate it to get the triangle

[fringe mantle]

wait - contiguous?

[elder kelp]

Contiguous

Idk man

I can't think straight give me a sec

[fringe mantle]

im not gonna lie, what is contiguous

[warm wigeon]

i get that the sides r the same but its so confusing to put into words to explain congruent sides

[elder kelp]

Are you sure you mean contiguous I can't see anything about 2 contiguous shapes on the Internet 😭

Oh so you mean congruent

[fringe mantle]

well then SAS no?

[warm wigeon]

yeah it's SAS but how do you explain it as a formal answer

[fringe mantle]

preferrably label the points

[elder kelp]

"The shapes are congruent through the SAS rule" then you label each vertex and just say for instance "AC is the same as CD because it is a square"
