what is an angle? : Definition #angle


[For a  video explanation click the link https://youtu.be/ejuoFUIyQJ0 ]




we often use the term ' angle ' in trigonometry, geometry etc. 'Angle' plays

an important role in mathematics. Everybody know angle30, 

angle 60,angle 15...etc.

  But the definitition of angle is disappear. Now we see what is angle?👇

                                 " ANGLE IS THE AMOUNT OF TURN OF A RAY FROM THE                                                            HORIZONTAL  LINE "
                                      
              The positions of rays at various angles are shown below

sin30=1/2 : what it means? 🤔 #sin30, #trigonometry

For a video explanation, click the link 👉  https://youtu.be/kXOzH8k_klw      we know sin30= 1/2.     what it means ?   🤔        In a right triangle if the sine of  angle  30  = 1/2   means that  "  the length of hypotenuse is always double the length of opposite side ". For Example ,  Suppose lenth of opposite side = 6 cm   then      lenth of its hypotenuse = 12 cm ***       Note :   If any one has any doubts in trigonometry or any mathematic concern topics please ask in the comment section .Also anybody of you want to give me friendly suggestions  post in the comment section. * what is dimension of an object? * 4th dimensional object Hypercube . * what is angle?   Page navigation #sin30 #= #1/2 #what #it #means #?  #maths #mathematics # trigonometry  #iit #jee #mains #eamcet #iit-jee #iitjee maths  #trigono...
