2. A circle can be displaced as the locus of
a point which moves at a specifics
distance from a specific distance from a
specific point
3. AB and ac are two chords of a circle and
the bisector of ˂BAC is a diameter of the
circle. Prove that AB=AC
4. B
C
DA
N
M
O
AB and AC are the equal chords. This chords join with point
A. AD is the bisector of ˂ BAC . O be the center of circle.
Therefore, ˂AMO = ˂ ANO = 90˚
˂MAO = ˂NAO ( Since AD is the bisector of ˂ BAC )
