Question 5

Which of the following is a precise definition of perpendicular lines?

Accepted Answer

Lines q and p are perpendicular if they meet at a single point and if one of the angles at the point of intersection is a right angle.

Answer

Lines q and p are perpendicular if they never meet.

Answer

Lines q and p are perpendicular if they intersect at the midpoint of q.

Answer

Lines q and p are perpendicular if they meet at a single point so that the two lines form a 'T'.

Question 6

Which student response is the most precise definition of a line segment?

Accepted Answer

A line segment is part of a line connecting two endpoints.

Answer

A line segment is when three points are all on the same line.

Answer

A line segment has an endpoint and continues forever in one direction.

Answer

A line segment is part of a line, not the whole thing.
