b)      Inscribed circle is any circle that lies ..........................tangent on the inside of a triangle........................................
 
Answer the Qs.
 
       a)  Where is the center of the circumscribed circle?
            ......................where the perpendiculr bisectors intersect................................................................................................
        b)How can you construct perpendicular bisectors?
            ......................draw a circle from two verteces of  a triangle, radius is the length of the side........................................................................
        c) What does „co-linear“ mean?
            .......................on the same line...................................................................................................
