<u>{{font color|brown|'''<big>Exploring symmetry with Geogebra</big>'''}}</u><br>
{{font color|brown|In this activity, you will explore lines of symmetry, reflection and rotation of objects.}}

===Objectives===
#Understanding rotation and reflection of geometric constructions
#Reflecting objects and drawing lines of symmetry
#Identifying lines of symmetry in given shapes visually
#Recognizing symmetric and non-symmetric objects

===What prior skills are assumed===
# Familiarity with the Geogebra application and tool bar
# Able to create different Geogebra sketches using the various functionalities - line, line segment, measurement of angles, measurement of segments, drawing polygons

===What resources do you need===
#Computer lab with projection equipment
#Handout for [[Learn Ubuntu|Ubuntu]]
#Handout for [[Learn LibreOffice Writer|LibreOffice Writer]]
#Handout for [[Learn Geogebra|Geogebra]]
#Geogebra files
#Handout for [[Learn Screenshot|screenshot]]
===What digital skills will you learn===
# Creating Geogebra files to explore mathematical concepts
# Inserting screenshots of Geogebra sketches in a text document and summarizing the mathematics investigation

===Description of activity with detailed steps===
====Teacher led activity====
Part 1- Locating and drawing lines of symmetry

Look at the following pictures with your teacher. Identify how many lines of symmetry are there.

</gallery>

Your teacher will demonstrate the following:
# [[Learn Geogebra|How to insert an image in Geogebra]]
# How to draw lines of symmetry to visually inspect symmetry?

Part 2 - Exploring ideas with symmetry with rotating and reflecting objects, in 2D and 3D

Your teacher will demonstrate the following to you in a Geogebra file:
# Drawing a line and rotating it
# Drawing a line segment and rotating it
# Creating reflections of objects
# Rotating polygons and creating new figures
The following Geogebra files will be used for this class.

====Student activities====
Part 1 - Locating and drawing lines of symmetry
#You can insert the images discussed with your teacher and draw the lines of symmetry
#In the previous activity on [[ICT student textbook/Drawing with Geogebra|Drawing with Geogebra]], you had made several geometric sketches. Open those sketches and examine the axes of symmetry in those figures.
Part 2 - Exploring symmetry with reflection and rotation
# Draw polygon shapes and rotate and reflect the polygon along a line or along a point. Explore what shapes you can produce.
# Use the regular polygon tool and rotate around a point to see what shapes are produced.

=== Portfolio ===
# Your Geogebra sketches will be part of the portfolio.
