Which of the following statements about line segments are correct?
3, ABC, DBC, DBA
3,BDA, ABC, BCD
3, CAB, BDA,BCD
3, ACB, BDA,BCD
A line segment is a part of a line which has two end points. Hence the length of a line segment is finite.
In a parallelogram ABCD, the diagonals bisect each other at O. If ∠ABC=30∘,∠BDC=10∘and∠CAB=70∘.
Find: ∠DAB,∠ADC,∠BCD,∠AOD,∠DOC,∠BOC,∠AOB,∠ACD,∠CAB,∠ADB,∠ACB,∠DBC and ∠DBA.
