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.

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

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

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