===Objectives===
=== 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 ===
Digital: Click here to [[:File:Parallel lines .ggb|open]] files
Non-digital : paper, pencil, ruler, protractor, compass
=== Process (How to do the activity) ===
#How to on/off computer ?
{{Geogebra|m7gxxkgb}}'''Procedure:'''
#How to open Geogebra application ?
# What are Parallel Lines?
#How to use tools in Geogebra interface?
# How can you tell that lines are parallel?
#How to create and Save a file in Geogebra ?
# Two lines ‘i’ and ‘h’ are parallel to each other
#How to plot and label points, draw line segments, draw line, draw rays ?
# 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?
