NCERT mathematics- Chapter 9: Areas of parallelograms and triangles

= Teaching Outlines =

Learning objectives
1. Parallelograms on the same base and between same parallels are equal in area.

2. Area of a parallelogram is the product of its base and the corresponding altitude.

3. Parallelograms on the same base and having equal area lie between same parallels.

Notes for teachers
These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.

Learning objectives
1. Triangles on same base and between same parallels have equal area.

2s. Area of a triangle is half the product of its base and the corresponding altitude.

3. Triangles on the same base and of equal area lie between the same parallels.

Learning objectives

 * 1) The segment connecting mid-point of any two sides of a triangle is parallel to the third side
 * 2) The length of the segment connecting the mid-point of two sides is equal to half the third side.
