Objectives

To construct a triangle with perimeter and base angles

Estimated Time

30 minutes

Prerequisites/Instructions, prior preparations, if any

Prior understanding of point, lines and angles, elements of triangle, properties of triangle

Materials/ Resources needed

Digital : Computer, geogebra application, projector.
Non digital : Worksheet and pencil
Geogebra files : “Triangle Construction(Perimeter-base angles)”

Download this geogebra file from this link.

Process (How to do the activity)

Use the slider to construct the perimeter
How do you get the 3 points required for the triangle
Why is the half angle constructed at each points
Perpendicular bisectors for the two segment formed due to the intersection of the half angles are constructed
What do these bisectors mark on the perimeter line
How is the required triangle formed using this method

Evaluation at the end of the activity

For what values of the angles the triangle is not formed.

-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 ===
-Content objectives  - what content areas
+To construct a triangle with perimeter and base angles
-Skill objectives - what specific skills
-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.
