1. let JE=JA =X , where x is a measure of a length in cm =6
a. deduce that triangle ABJ is a right isosceles triangle.
2. (JB) cuts (c) in a second point F.
prove that F is tge midpoint of (JB) and that (FO) is the perpendicular bisector of (AB)
5. let L be a point on (EJ) such that (EL) =2.4 . show that (OE) parallel to (AL)​
