Transcript

00:00

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

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
