===Name of the activity===
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 ===
To demonstrate things which are equal to the same thing are equal to one another
===Estimated Time===
15 minutes
=== Prerequisites/Instructions, prior preparations, if any ===
Prior knowledge of point, lines, angles, parallel lines
===Materials/ Resources needed===
* Digital : Computer, geogebra application, projector.
* Non digital : Worksheet and pencil
* Geogebra files : “[https://ggbm.at/w5abppzb Axiom-1.ggb]”
{{Geogebra|w5abppzb}}
===Process (How to do the activity)===
* The file demonstrates the first Euclid's axiom.
* The measures of all the lines corresponds to the distance between 0 of x-axis to point F.
* If the distance of point F from 0 is increased or decreased the lengths of all the lines also varies accordingly this can be done by using the slider '''Distance'''.
* Since all the lines measure the same distance (0 to point F), the lines are equal to each other.
* Record the segment lengths in the worksheet
: {| class="wikitable"
|Position of Distance
|0 - Point F
|Length BC
|Length GH
|Length DE
|Length IJ
|-

'''Evaluation at the end of the activity'''
* Can you conclude if all the lines are equal to a measure on x- axis then they are equal to one another.
