Parallel lines are lines that are always the same distance apart. Because they are always the same distance from one another, parallel lines will never intersect.

Objectives

Introduce parallel lines

Understand perpendicular distance between parallel lines

Estimated Time

20 minutes

Prerequisites/Instructions, prior preparations, if any

Prior knowledge of point, lines, angles, intersecting lines, vertically opposite angles

Materials/ Resources needed

Digital : Computer, geogebra application, projector.
Non digital : Worksheet and pencil.
Geogebra files : Parallellines-1.ggb

Download this geogebra file from this link.

Process (How to do the activity)

Prior hands on activity: Draw two lines which are parallel in the file to ask will these lines meet.
Use the file to seek the initial observations from children – if the lines will ever meet
Is it possible for two lines to never meet.
How do you know if they will meet at certain point?
Drag the screen on either sides to show the two lines never meet.
Inquire if measuring the distance between the two lines will determine if the lines will meet.
Plot two points on the lines and join them
Draw two parallel lines
What do you notice about these lines
Note the distance between the two lines
Introduce concept of transversal : Draw two lines with transversal – how can you say that the two lines are parallel.
For the parallel lines identify the interior region and exterior region.

+Parallel lines are lines that are always the same distance apart. Because they are always the same distance from one another, parallel lines will never intersect.
-Brief blurb describing what the activity.  If this has been borrowed from some external web site (for example, a non OER or OER site which had this idea and based on which the activity was developed)
 === Objectives ===
-Content objectives  - what content areas
+Introduce parallel lines
-Skill objectives - what specific skills
+Understand perpendicular distance between parallel lines
-Classroom objectives - to demo peer learning, to make a classroom resource, etc -
-All these kinds of objectives need not be there for every activity.  And no need to list them as different headings.  This is only for our reference when we are developing activities.

+* Use the file to seek the initial observations from children – if the lines will ever meet
-What kinds of questions you can ask for that activity
+* Is it possible for two lines to never meet.
+* How do you know if they will meet at certain point?
-What are the student follow-up activities/ questions you can give?
+* Drag the screen on either sides to show the two lines never meet.
+* Inquire if measuring the distance between the two lines will determine if the lines will meet.
