Exploring Parallel and Perpendicular Lines

What does it mean when lines are described as parallel?

• They intersect at one point.

• They are always curved lines.

• They never meet and are always the same distance apart.

• They intersect forming a right angle.

What symbol is used to denote that two lines are perpendicular?

• A horizontal line.

• A pair of crossed lines.

• A single vertical line.

• An upside-down capital T.

Which of the following is not a correct representation of a line segment?

• A line with two arrows at each end.

• A line with a bar on top and no arrows.

• A line with an arrow on one end.

• A line with no arrows or bars.

In the context of the lesson, what does a line with arrows on both ends represent?

• A point

• A line segment

• A ray

• A line

What is the geometric shape formed at the intersection of two perpendicular lines?

• An obtuse angle

• A circle

• A right angle

• A triangle

Which of these is an example of parallel lines?

• The edges of a book.

• Diagonals of a rectangle.

• Crossing paths in a park.

• Adjacent sides of a square.

What is the correct way to denote that line LM is parallel to line JK?

• LM >< JK

• LM -- JK

• LM || JK

• LM = JK

Which of the following is true about skew lines?

• They are parallel and in the same plane.

• They intersect at one point.

• They intersect forming a right angle.

• They do not intersect and are not in the same plane.

How can you verify if two rays are perpendicular using everyday objects?

• Using the corner of a book.

• Using a circular protractor.

• Using a flexible tape.

• Using a triangular ruler.

What type of angle is formed by perpendicular lines?

• Straight angle

• Right angle

• Acute angle

• Obtuse angle
