Question

AB and CD intersect at point O such that AO=OB and OC =OD . find the third pair of corresponding parts to make the two triangles congruent by side angle side . write the congruence of two triangles in the symbolic form​

Answer 1

Answer:

In ∆ACO and ∆DOB

AO = OD (given)

OC = OB (given)

<AOC = <BOD (vertically opposite angel)

So, by SAS (side angle side) congruency rule

∆ACO ≈ ∆DOB
