Step-by-step explanation:
HJ ≅ JH, by symmetric property of equality.
ΔGHJ ≅ ΔIJH, by SAS congruence.
GJ ≅ IH, corresponding parts of congruent triangles are congruent.
it is proven congreunt ASA axiom
<m=<m(given)A
MN=MN(common side)s
<o=<o(given)A
Distance sqrt of (x2-x1)/(y2-y1).
Distance = sqrt of 8/-7
Hope this helps!
