Answer 1

I believe so,

Answer 2

no just isosceles so what mean this ?

Answer 3

what mean isosceles ?

Answer 4

do you mean whats the definition of isosceles or something?

Answer 5

Answer 6

i honestly do not know....

Answer 7

two sides are equale ,yes ?

Answer 8

yes...

Answer 9

so in this case what mean this ?

Answer 10

so that AB = BC

Answer 11

oh, okay

Answer 12

and now can you calculi he h ?

Answer 13

the h

Answer 14

no =\

Answer 15

this is a right triangle so you can using here pythagora

how ?

Answer 16

do you know pythagora's theorem ?

Answer 17

no

Answer 18

h^2 = AB^2 + BC^2

Answer 19

can you calculi it ?

Answer 20

h^2 = 8^2 +8^2

h^2 = ?

Answer 21

128

Answer 22

h^2 = 64 +64

h^2 = 128

yes but this is h squared and you need getting just h

Answer 23

than

h= sqrt128 = ?

Answer 24

11.313708499 ?

Answer 25

yes but you need using

h=sqrt128 = sqrt(64*2) = 8sqrt2

h=8sqrt2

do you understand it now

but you can calculi h in a different ,second way too

using sin45 or cos45

do you know it how ?

Answer 26

yes, thank you.

Answer 27

ok

yw
