Question

when two coplanar figures coincide with
figures. We know that two ungles of equal measure are congruent,
Similarily, are two arcs of the same measure congruent?
Find the answer of the question by doing the following activity
Activity:
Draw two circles with centre C, as shown in the figure. Draw Z DCE, Z FCG of
the same measure and Z ICI of different
measure.
C/70°
F
400
70"
B
Arms of Z DCE intersect inner circle
at A and B.
Do
you
notice that the measures of
arcs AB and DE are the same? Do they
coincide ? No, definitely not.
Now cut and seperate the sectors
C-DE; C-FG and C-LJ. Check whether
А)
E
D
The
Fig. 3.31
the arc DE, arc FG and arc IJ coincide with each other.
Did you notice that equality of measures of two arcs is not enough to make the two
arcs congruent? Which additional condition do you think is neccessary to make
the two arcs congruent ?
From the above activity -
Two arcs are congruent if their measures and radii are equal.
'Arc DE and arc GF are congruent' is written in symbol as are DE = arc GF.​
