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

Understand formation of triangles
Recognize elements of triangle
Introduce concepts of exterior angle.

Estimated Time

Prerequisites/Instructions, prior preparations, if any

Prior knowledge of point, lines, angles, parallel linesResources needed

Materials/ Resources needed

Digital : Computer, geogebra application, projector.
Non digital : Worksheet and pencil
Geogebra files : “Introduction to a triangle.ggb”

Process (How to do the activity)

Use the geogebra file to illustrate.
How many lines are there? Are the lines meeting?
Are the two lines parallel? How can you say they are parallel or not?
How many angles are formed at the point of intersection?
What is the measure of the total angle at the point of intersection of two lines?
Of the four angles formed which of the angles are equal? What are they called?
Do the three intersecting lines enclose a space? How does it look? It is called a triangle.
What are the points of intersection of these three lines called?
The line segments forming the triangle are called sides.
How many angles are formed when three lines intersect with each other?
How many angles are enclosed by the triangle?

 === Objectives ===
-Content objectives  - what content areas
+#Understand formation of triangles
+#Recognize elements of triangle
-Skill objectives - what specific skills
+#Introduce  concepts of exterior angle.
-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.
