(a) Consider the statement.
If a line intersects a segment at right angle, then the line forms an angle of 90° with the segment.
If a line forms an angle of 90° with a segment, then the line is perpendicular to the segment.
The law of
can be used to draw a valid conclusion.
Part B
If any law of logic is applicable to the above statement then what is the possible conclusion?
(b)
A No conclusion can be drawn
® If a line intersects a segment at right angle, then the line is not perpendicular to the segment
If a line intersects a segment at right angle, then the line is perpendicular to the segment.
If a line does not intersects a segment at right angle, then the line is not perpendicular to the segment
