Based on the information, determine which sides of quadrilateral ABCD must be parallel m angle A= 67°, m angle b = 120°, m angle c=73°, m angle d =100°

None of the sides are parallel.

Step-by-step explanation:

Quadrilaterals are all figures or shapes bounded by four sides. Some common examples are: square, rectangle, trapezium, rhombus, parallelogram etc.

Two or more lines are said to be parallel, if none of the lines meet when extended till infinity. i.e they are at to one another.

Given a quadrilateral ABCD with the measures of angles as given, none of its sides would be parallel.
