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.

3. eli123

yeah i did that i just wanted my answers to be checked

4. eli123

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

5. hartnn

sum of the squares of the length of the legs is incorrect

6. hartnn

how did u get 45 ?

7. eli123

8. hartnn

65 is correct

9. hartnn

u wrote 45 there

10. hartnn

area is incorrect

11. eli123

so they are both 65 and area 10.67?

12. hartnn

they are both 65 <----correct area is not 10.67

13. hartnn

what are the lengths of legs u got ?

14. eli123

i have d(A,B)=4 d(b,c)=sqrt65 and d(a,c)=7

15. hartnn

yes, so legs are 4 units and 7 units area is half the product of legs

16. eli123

14?

17. hartnn

yup

18. eli123

can you check something else for me? last one

19. hartnn

sure

20. eli123

21. hartnn

not symmetric w.r.t y axis (-2,0) is correct

22. eli123

no? then which one?

23. hartnn

if u flip the upper half and lower half, u get the same graph, here x-axis remains axis of symmetry

24. eli123

hmm i see

25. eli123

so (3,0) would be x-axis too?

26. hartnn

sorry what ? where does 3,0 come from ??

27. eli123

its another example lol

28. hartnn

ok.
