√5 Pythagoras theorem se bnega n... To h² = p² + b² hota h or h² = 1² + (2)² hoga (bcoz.. perpendicular is always 1) then h² = 1 + 4 h² = 5 So, h = √5.... Now, base hmne 2 liya tha to number line me 0 to 2 lenge or fir us pr √5 right angle triangle means 90° bna kr represent krenge... 😅😅 Maybe aap yhi puchh rhe the...!!
Sir kya ham hamesha 1 unit distance lete hai jahan se perpendicular cut kartein hai ..
Anyone tell me that root 5 ko represent kerne ke liye hame 2unit hi leni hai asesa kyu kaha sir ne ham 1 unit bhi to le sakte the ya phir 3 unit

Dear sir
Sir is 22/7 rational or irrational as my school Maths teacher keeps saying that it is irrational number as it's decimal expansion is never ending . But according to my understanding 22/7 should be a rational number as it is in the form of p/q
@MagnetBrainsEducation
Жыл бұрын
Hi there! You're right that 22/7 is a rational number, as it can be expressed in the form of p/q. It's important to remember that irrational numbers have decimal expansions that are never ending, so 22/7 would not fit that criteria. Keep up the great work!

Your Sir is talking about Pi, Pi is an irrational number whose exact value is non terminating non reccuring, i.e.; 3.1415926.... But when you divide 22 by 7, you get 3.1428.... that is near the value of Pi. We take 22/7 as APPROXIMATE value of Pi, it is not actual value of Pi. And yes, 22/7 is a rational number. Therefore, Pi is Irrational and 22/7 is Rational...Well Magnet Brains' comment should have added this information.......
