December 02, 2020Class 7, Class 8, Class 9 No comments

Experimental verification in Mathematics affords new thoughts and trends of predominant significance to these working in the subject of mathematical education. It seeks to mirror each range of lookup worries inside this subject and the variety of techniques used to learn about them. It presents with didactical, methodological, and pedagogical subjects, as an alternative to special programs for instructing mathematics.

Vertically opposite angles are equal.

Question and its solution:

2. Sum of straight angles is 180°.

Construction of Angles

September 08, 2020Class 5, Class 6, Class 7, Class 8, Class 9 No comments

→Construction of 60°

↳Draw a line PQ.

↳Take P as centre and with suitable radius(of any measurement), draw an arc XY that cuts PQ at X.

↳With the same measurement of PX, draw an arc from X to cut the previous arc XY and label that

intersected point as R.

↳Join P and R then produce(Upto any length) it to get PO.

Here, ∡OPQ is required conctruction.

Pythagoras Theorem

August 27, 2020Class 7, Class 8, Class 9, Class Ten, Opt. Maths(8) No comments

Pythagoras Theorem:In any right angled triangle, the square made on the longest side (Hypotenuse) is equal to the sum of the squares made on the remaining two sides (Perpendicular and Base).

Mathematically:

1) h² = p² + b²

Similarly:

2) p² = h² - b²

3) b² = h² - p²

Square and Square Root (Exercise)

August 24, 2020Class 5, Class 6, Class 7, Class 8, Square and Square root No comments

Square of a number : When a number is multiplied by itself then that product is called square of a number.

For example: Square of 3 = (3)² = 3x3 = 9

Note: Square of negative number is always positive.

For example: Square of (-5) = (-5)² = -5 x -5 = (+ 25)

Square Root : When a number is multiplied by itself to get the original number, then it is called square root. It is denoted by the symbol √ (Tick) called radical.

For example: Square root of 9 = √9= √3x3 = 3
