explanation on proving similarities

[hazy delta]

How can I explain this?

I know it shows the answer there but how would I word it?

[fierce shore]

The triangles can only be similar if they have the same angles so

[soft gyro]

so < BAC = 62

[fierce shore]

U find the angles e.g.

DCE = 72 because opposite angles are equal

for the other angles u can just say angles in a triangle add up to 180 degrees

[soft gyro]

im assuming < ECD = < ACB

for that same reasoning

[soft gyro]

and yes ^

[fierce shore]

yh

[hazy delta]

theyre equal because theyre vertically opposite right?

[soft gyro]

yep

thats exactly it

[hazy delta]

so can i say that for my proof?

[soft gyro]

yes

[fierce shore]

mhm

[hazy delta]

"angle ecd is equal to angle acb because they are vertically opposite"

[soft gyro]

yep

[hazy delta]

but how would that show they are similar?

[soft gyro]

or you can do < ecd = < acb

[soft gyro]

they have the same int angles

[hazy delta]

and what does it mean by "completes proof"

[fierce shore]

if a triangle shares the same angles with another triangle

they are similar

[hazy delta]

oh right

AAA

[soft gyro]

just a final statement and all your explanation

[fierce shore]

it doesnt matter the positions of the angles

[fierce shore]

no thats congruency

[soft gyro]

would be AAA in this case

[soft gyro]

but yeah

[fierce shore]

similarity is always angles dont get mixed up

[hazy delta]

okay tysm

this helped

[soft gyro]

sn boss

[fierce shore]

np

if you need any help open another thread but otherwise /solved
