- 00:01
Okay sy shmoop er's get couple triangles for you okay
- 00:06
strangle one trial tour Khun growing here with theorems proved
- 00:09
that there Khun grew it Well to prove anything khun
- 00:16
grew int we need all the information we can muster
- 00:19
about that thing We just look at all the information
Full Transcript
- 00:21
and see if we know all that we need to
- 00:23
know to use a psa s a s or a
- 00:27
s to prove both triangles are khun grew int right
- 00:31
side side angle ingleside side All that stuff Okay start
- 00:33
with triangle one Well since it has khun grew int
- 00:36
marks on two sides we can deduce it's an ice
- 00:39
oscillates triangle So the base single must also be khun
- 00:42
grew in right These three angles have tto add upto
- 00:45
one eighty So i saw sleaze triangle missing bass angles
- 00:48
using angle something room we can find the missing bass
- 00:51
singles like we just did here Fifty degrees and then
- 00:53
to ex since two x of one thirty and your
- 00:56
ex or sixty five years let's think about triangle to
- 00:59
while here's sixty five degrees What do you think So
- 01:02
it too is a nice sauce elise trying on its
- 01:04
legs or khun grueling with those of triangle one Both
- 01:07
base angles are sixty five degrees while doing a bit
- 01:10
of math and the angle Some theory Again we can
- 01:13
figure out the measure of the last remaining angle of
- 01:16
triangle to here So we've got six five degrees and
- 01:19
sixty five degrees and what is one eighty Well guess
- 01:22
what it's Fifty degrees So we have two sets of
- 01:25
khun group corresponding sides and three pairs of congruent corresponding
- 01:29
angles G this means we can prove congruence This means
- 01:33
we can prove khun grew into by c s r
- 01:36
a s or roll in which everyone we want That
- 01:39
means the correct answer is all of the above in 00:01:42.045 --> [endTime] that state
