Hint: You must use the following theorems. 1) Distance formula for finding the lengths of all the sides. 2) Pythagorean theorem for confirming that we have a right triangle. 3) Heron's formula for finding area.
yeah i did that i just wanted my answers to be checked
for the sum of the squares of the length of the legs i got 45 and for the square of the lenght of the hypothenuse i got 45 then the area i got 10.67
sum of the squares of the length of the legs is incorrect
how did u get 45 ?
i meant 65 my bad
65 is correct
u wrote 45 there
area is incorrect
so they are both 65 and area 10.67?
they are both 65 <----correct area is not 10.67
what are the lengths of legs u got ?
i have d(A,B)=4 d(b,c)=sqrt65 and d(a,c)=7
yes, so legs are 4 units and 7 units area is half the product of legs
can you check something else for me? last one
not symmetric w.r.t y axis (-2,0) is correct
no? then which one?
if u flip the upper half and lower half, u get the same graph, here x-axis remains axis of symmetry
hmm i see
so (3,0) would be x-axis too?
sorry what ? where does 3,0 come from ??
its another example lol
