==== Concept 1: Formation of a triangle, elements of a triangle and its measures ====
  −
# A triangle is a three sided closed figure.
  −
# It is one of the basic shapes in geometry.
  −
# It triangle is a polygon with three edges and three vertices.
  −
# There are three angles in a triangle formed at the three vertices of the triangle.
  −
# Interior and exterior angles in a triangle at a vertex, together form a linear pair.

===== Activities =====
# [[Formation of a triangle]]: A plane figure formed by three intersecting lines.
+
# Students can learn about the history from their grand parents or elders in their families. They can make a chart of the events based on their learning.  
# [[Elements of a triangle]]: Terms that are associated with triangle.
+
# Students can make family tree taking help from their parents.  
# [[Measures in triangle]]: Parameters that are measured in a triangle.
+
# Students can learn how different professions have evolved over time from the elders in family or from their teachers.  
# [[Interior and exterior angles in triangle]]:  Angles formed when a triangle is formed.            [[Category:Triangles]]

== Concept 2: Types of triangles based on sides and angles ==
  −
'''Types of triangles based on angles in the triangle'''
  −
# Acute triangles are triangles in which the measures of all three angles are less than 90<sup>o</sup>.
  −
# Obtuse triangles are triangles in which the measure of one angle is greater than 90<sup>o</sup>.
  −
# Right triangles are triangles in which the measure of one angle equals 90 degrees.
  −
'''Types of triangles based on sides in the triangle'''
  −
# Equilateral triangles are triangles in which all three sides are the same length.
  −
# Isosceles triangles are triangles in which two of the sides are the same length.
  −
# Scalene triangles are triangles in which none of the sides are the same length.
