=== Objectives ===
Students will be able to identify parallel and intersecting lines.

=== Estimated Time ===
20 minutes

=== Prerequisites/Instructions, prior preparations, if any ===
Knowledge about  line, line segment

=== Materials/ Resources needed ===

Non-digital : paper, pencil, ruler, protractor, compass

=== Process (How to do the activity) ===
{{Geogebra|m7gxxkgb}}'''Procedure:'''
# What are Parallel Lines?
# How can you tell that lines are parallel?
# Two lines ‘i’ and ‘h’ are parallel to each other
# Identify parallel lines which do not have a common meeting point in the same plane
# Identify parallel lines do not intersect if extended till infinite in both the directions.
# Measure the distance between the lines and identify the equidistance (move point 'G') between the parallel lines
# Students will use sticks or straws to create parallel line segments. They will prove the line segments are parallel by measuring the distance between the line segments.
# What are intersecting lines?
# Identify intersecting lines (two or more) meet only at one point always and also can cross each other at common vertex (which is the point of intersection).

=== Evaluation at the end of the activity ===
# What is the difference between parallel and intersecting lines?
# Can parallel lines also be intersecting lines?
