1.	Third questions answer with full explanation
Answer» Step-by-step explanation: 1ST picture is a parallelogram Sum of opposite angles is 180 degrees 105+ 75= 180 so 1st one is parallelogram 2nd picture is ALSO parallelogram Because opposite sides are equal PS = QR and PQ=RS 2nd picture is also a parallelogram 3rd picture is not a parallelogram Because for parallelogram OX = OZ and OY= OT but here in this picture OX is not equal to OZ and OY is not equal to OT

Answer»

Step-by-step explanation:

1ST picture is a parallelogram

Sum of opposite angles is 180 degrees

105+ 75= 180

so 1st one is parallelogram

2nd picture is ALSO parallelogram

Because opposite sides are equal

PS = QR and PQ=RS

2nd picture is also a parallelogram

3rd picture is not a parallelogram

Because for parallelogram

OX = OZ and OY= OT

but here in this picture OX is not equal to OZ

and OY is not equal to OT
