Answer 7

A

Answer 8

I'm not sure-

Answer 9

Like I know it's A now.. but why?

Answer 10

A

Answer 11

i said A already

Answer 12

I know but why is it A so I know

Answer 13

oh ok first do you know what all of those means equilateral,
scalene, isosceles,scalene

Answer 14

Not 100% no

Answer 15

Equilateral means all of the angles are the same length and a triangle has all the same lengths so i would say either B or A

Answer 16

so which one do u think A or B

Answer 17

Not all triangles have the same length.. @ganeshie8 ?

Answer 18

yay i know

Answer 19

coolgirl's explanation looks good ! a right triangle can never be equilateral because all angles in an equilateral triangle are 60. but a right triangle need to have a 90 degree angle

Answer 20

yay i know thats why i said it might be B

Answer 21

Oooh, I get it.

Answer 22

awesome

Answer 23

So what does isosceles and scalene mean?

Answer 24

i am right A

Answer 25

Isosceles means all of them are different length

Answer 26

equilateral : all sides are equal
isosceles : atleast two sides are equal
scalene : no sides are equal

Answer 27

Oh okay!

Answer 28

oh right i got both mixed up sorry

Answer 29

So like..

Answer 30

would this be isosceles, acute?

Answer 31

or obtuse? (why? I kinda forget this part too.. :/ )

Answer 32

that looks more like isosceles-obtuse wid that fat angle

Answer 33

What angle? how do you tell?

Answer 34

What do the lines mean?

Answer 35

obtuse triangle has an obtuse angle

Answer 36

small dashes on sides tell us that both sides have equal length

Answer 37

its like you and your friend going to a party wearing same color dress

Answer 38

oh right i got both mixed up sorry

Answer 39

ppl will know you both are related as you both are in same color dress

Answer 40

Can you outline the angle you see? I'm still kind of confused on how you know it's obtuse rather acute.. I don't know the difference though..

Answer 41

um

Answer 42

@ganeshie8

Answer 43

ok!
