PROPERTIES OF TRIANGLE

 TRIANGLE AND ITS PROPERTIES


Let A, B, C be three distinct non-collinear points. The figure formed by three line segments AB, BC, CA by joining these non-collinear points A, B, C in pairs, is called Triangle.
PROPERTIES OF TRIANGLE
                                                                         
    1.   Sum of angles of a triangle is 180°. This property is called angle-sum property of triangle.

    2.   In a triangle the exterior angle is equal to the sum of opposite interior angles. Therefore, exterior angle is always greater than each interior angle.

    3.   The sum of any two sides of the triangle is always greater than the third side.

CORRELATION OF MATHEMATICS WITH OTHER SUBJECTS

Image
        Mathematics correlates with almost all school subject. Sciences uses mathematics the most. Even the Fine Arts use mathematics to some extent. Mathematics has characteristics like symmetry, similarity, originality, generalization and verification. All these characteristics make mathematics very usable, practical and versatile. Relation of mathematics with science, economics and fine arts is covered in this text Relation of Mathematics with Sciences       1. Physics  -           (i) The numerical derivations of many Laws of science are provided by mathematics.      (ii) Newton Laws of Motion, Gravitational Laws, Boyle's Law, Charles Law etc. require mathematics for practical understanding.          (iii)  All measurements, units and measuring devices depend upon mathematics.            2.  Chemistry -        (i) Chemical equations, balancing of equations       (ii) Atomic number, atomic and molecular mass, atomic mass units, radii of atoms and molecules.        (iii) Chemica

MATH PROBLEM SOLVING

SOLVING A PROBLEM OR PROBLEM SOLVING IN MATHEMATICS             I have a problem, I want to solve it. Say the problem is - Who Shaves the Barber?  To solve this, do I need mathematics? The answer is No. I just need to ask the barber and the problem will be solved. Lets take another example. I want to go on a vacation for 5 days. For that I have to take a leave, select a place for vacation, check how much money is required, check booking dates with hotel, decide mode of transport and make a time-plan of visits to different places during vacation. Now the question arises, "Do I need mathematics?" The answer is Yes. Money required, dates, distance to travel and time-plan need mathematics. This is the real life example of problem-solving in mathematics. For this you have to think, plan, reason out, apply logic and solve the problem systematically.              Writing solution and finding solution are two different scenarios. Writing a solution means solving a problem without th

OBJECTIVES OF TEACHING MATHEMATICS

Image
INSTRUCTIONAL AND BEHAVIOURAL OBJECTIVES   Instructional Objectives  1. These are the statements of measurable learning that is intended to take place as a result of instruction. 2. These are set according to the level of students in a particular class. 3. These are classroom objectives unique to each course or subject. 4. These are derived from the terminal behaviour which the students are expected to display as a consequence receiving instruction. Behavioural Objectives 1. These are the objectives in terms of behaviour of the students. 2. These are description of observable student behaviour related to learning. 3. Behavioural objectives should identify the following    (i) Learner - for whom the objectives are written.     (ii) Behaviour - targeted for change.    (iii) Conditions - under which the behaviour will be performed.    (iv) Criteria - for the acceptable performance of behaviour to occur.   EXAMPLE TOPIC - PYTHAGORAS THEOREM I. COGNITIVE OBJECTIVES    1. To state
