### Transcript

and see if we know all that we need to

know to use a psa s a s or a

s to prove both triangles are khun grew int right

side side angle ingleside side All that stuff Okay start

with triangle one Well since it has khun grew int

marks on two sides we can deduce it's an ice

oscillates triangle So the base single must also be khun

grew in right These three angles have tto add upto

one eighty So i saw sleaze triangle missing bass angles

using angle something room we can find the missing bass

singles like we just did here Fifty degrees and then

to ex since two x of one thirty and your

ex or sixty five years let's think about triangle to

while here's sixty five degrees What do you think So

it too is a nice sauce elise trying on its

legs or khun grueling with those of triangle one Both

base angles are sixty five degrees while doing a bit

of math and the angle Some theory Again we can

figure out the measure of the last remaining angle of

triangle to here So we've got six five degrees and

sixty five degrees and what is one eighty Well guess

what it's Fifty degrees So we have two sets of

khun group corresponding sides and three pairs of congruent corresponding

angles G this means we can prove congruence This means

we can prove khun grew into by c s r

a s or roll in which everyone we want That

means the correct answer is all of the above in 00:01:42.045 --> [endTime] that state
