=== Objectives===
−
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)
+
* To construct a triangle given two sides and an angles
−
 
+
* To understand the given angle should be included angle when two sides are given
−
=== Objectives ===
  −
Content objectives  - what content areas
  −
 
  −
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.

===Process (How to do the activity)===
 
===Process (How to do the activity)===
−
How to do the different steps of the activity?
+
* For given angles and sides, which parameter will you start the construction with.
−
 
+
* If the given angle is drawn first what are the next steps of construction.
−
What kinds of questions you can ask for that activity
+
* How many triangles are possible if the triangle is drawn such that the given angle is not included angle ( - if the second side is not marked along the arm of the angle but from  point B)
−
 
+
* If you start the construction with a given side which of the other two parameters should be taken next  to complete the required triangle.
−
What are the student follow-up activities/ questions you can give?
+
'''Evaluation at the end of the activity'''
−
 
+
* How many triangles are possible for given 2 sides and an angle?
−
Categories:  (Subject) (Topic) (Sub-concept/topic) (Class 6) (Resource format)
+
* What is the additional condition that is required to be specified if 2 sides and 1 angle is given for constructing a triangle?
