Question

State the three pairs of equal parts in ΔAOC and ΔBOD.

Answer 1

Answer:

i) The three pairs of equal parts in two triangles AOC and BOD are:

CO = DO (given)

OA = OB (given )

\angle COA = \angle DOB ( As opposite angles are equal when two lines intersect.)

ii) So by SAS congruency rule,

\Delta COA \cong\Delta DOB

that is

\bigtriangleup AOC\cong \bigtriangleup BOD

Hence, option B is correct
