Thank you We sneak and here's your shmoop du jour
- 00:05
Brought to you by congruent triangles It just feels like
- 00:08
they're up to something We're still trying to figure out
- 00:11
their angle All right check out these figures right here
- 00:15
Triangle c a b in an mp or shown in
Full Transcript
- 00:17
a diagram above If angle c is khun grew into
- 00:20
angle end what additional information would be sufficient to prove
- 00:24
that triangle c a b is khun grew into triangle
- 00:27
an mp And here a potential answers right Angle angle
- 00:32
So we've got two triangles and we're supposed to figure
- 00:34
out what additional info we need to prove that there
- 00:36
are same z's sort of like those identical twins whose
- 00:39
parents dress him you know to look exactly alike No
- 00:42
no emotional scars there Well we've got a handful of
- 00:46
ways approving Khun grew int their side side side side
- 00:49
angle side angle ingleside and ingleside angle All these require
- 00:53
exactly three pieces of critical information so we can immediately
- 00:57
nick's option a we know one angle but they only
- 01:00
gives us one more piece of the puzzle and that
- 01:02
ain't going to cut the mustard So adios Option a
- 01:05
Be tells us that angle b is khun growing tangle
- 01:07
p and the angle is concluded toe angle m well
- 01:11
nifty but there is no angle angle angle option Just
- 01:14
because we know all three angles air concluded that we
- 01:17
could still have in anybody triangle or the triangle that
- 01:21
eight new york so yeah can be then there see
- 01:24
which says that line c a is khun grew in
- 01:27
tow line and and and line a bee is khun
- 01:30
grew in tow line and pee Okay so we've got
- 01:33
two sides and one angle Looks like we'd be using
- 01:36
side ingleside right Well yeah but the words aaron that
- 01:40
order for a reason People procida ingleside the work the
- 01:43
angles that we know where khun grew it must be
- 01:46
in between The two sides we know are congruent and
- 01:48
that isn't the case here We've got this angle but
- 01:51
these two lines so unfortunately see tells us not about
- 01:54
the congregants of the triangle So bye bye Which means
- 01:58
the answer is d angle b is khun grew into
- 02:00
angle p inline c b is khun grew tow line
- 02:03
n p here we've got two angles and one side
- 02:06
With sides We know where khun gruen appearing in between
- 02:08
the two angles We know where khun growing which uses
- 02:11
the angle side angle the're um to prove that the
- 02:13
triangles themselves also arkin grueling Now that we know they're
- 02:17
spitting images of one another let's put him in matching
- 02:20
outfits and take him out in public Were hoping the 00:02:22.923 --> [endTime] wind parents of the year this one
