Triangle and its types and defination in hindi

                 Trigonometry - 2

Hello friends ! Maine apne last post Trigonometry ka basic concept in hindi  me triangle k baare me short me kuch chije batayi thi.Aaj mai triangle k baare me details me bataunga. Agar aap triangle k baare acche se details me jaanana chhahate hai to iss post ko pura read kare. 
Triangle me hum jaanege ki-:

• Triangle kya hai ?
• Triangle k kitane types hote hai?
• Sides k basis par triangle kitne types k hote hai?
• Angle k basis par triangle k kitane types hote hai ?

Etc.
【Note-: Ye  sab k alawa koi oar baate jo aap triangle k baare me jaanana chahate hai .Mujhe comment kare .Mai issi post aapk  name sahit iss post me add kar dunga.】

Chaliye ab aage badate hai, to friends first question hai ki-:

Q-1. Triangle kya hai?

(What is triangle ?)

Friends Triangle ek aisa shape hai jisme 3 line segment hote hai . Ye line segment ek dusre se attached hote hai.
Means triangle 3 line segment se plane par banaya gaya ek close shape hai.
Agar aap simple language me kahe to -
" triangle ek aisa shape hai jisme 3 lines ek dusre se judi (attached) rahati hai."
                           Or
" Wo shape jisme only 3 angles ho , triangle  kahalata hai."

Triangle ko " ∆ "  se denote karte hai.

Niche ek triangle ka image diya gaya hai
Some important points of triangle-:

Uppar diye gaye image me triangle ko aap dhyaan se dekhe. Uppar diye triangle k anusaar triangle k some important points hote hai. Jo iss prakaar hai-:
1. Uppar image k triangle ABC ko
      hum ∆ABC se denote karte hai.
2. ∆ABC me 3 sides hai -:
      AB , BC and CA
3. Iss triangle me 3 corners hai-: A,
    B and C. Inn corners ko hum vertices kahate hai.
Hindi me vertices ko " Shirsh" (शीर्ष)  kaha jata hai.
4. Triangle me 3 angle hote hai-:
    /_ A , /_B  and  /_C
5. Kisi bhi triangle k sabhi 3 Angeles      ka sum (Addition) 180° hota hai.
Means , /_A+/_B+/_C = 180°

Types of triangle-:

 Triangle k types ko hum 2 base (aadhar) par defined kar sakte hai-
(i) Angle k aadhar par  triangle k types
(ii) Sides k aadhar par triangle k types

(i) Angle k aadhar par triangle k types-:

Friends"angle k aadhar" par triangle k 3 types hote hai -

(a) Acute angled triangle

(b) Right angled triangle
(c) Obtuse angled triangle

(a) Acute angled triangle-:

Acute angled triangle ko hindi me " nyunkon tribhuj" ("न्यूनकोण त्रिभुज ") kahate hai.
Defination of "acute angled triangle" -:
Wo triangle jisme sabhi angle 90° se less  ho, matalab 90° se kam ho. To aise triangle ko hum "acute angled triangle" kahate hai.

For example-:

Niche diye triangle ko dekhe-:

∆ABC me hum dekhate hai ki -:
/_ A = 60°
/_B = 65°
/_C = 70°
∆ABC ka  sabhi angle 90° se less hai. Isliye ∆ABC ek Acute angled triangle hai.

(b) Right angled triangle-:

 Right angled triangle ko hindi me "samkon tribhuj"(समकोण त्रिभुज)  kahate hai.
Defination of "Right angled triangle"-:
Wo triangle jisme koi ek angle 90° ho, to aise triangle ko "right angled triangle" kahate hai.

For example-:
Niche diya triangle dekhe.

∆ABC me ,  /_ C = 90°
Isliye ∆ABC , ek Right angled triangle  hai.

• Multiplication of three digits number in hindi

(c) Obtuse angled triangle-:

Obtuse angled triangle ko hindi me "Adhik kon tribhuj"(अधिककोण त्रिभुज)

kahate hai.

Defination of  "Obtuse angled triangle"-:

Wo triangle jisme koi   ek angle 90° se greater ho . Means 90° se big ho. To uss triangle ko hum " obtuse angled triangle" kahate hai.

For example-:

∆ABC me ,

/_C = 120°

Isliye ∆ABC ek obtuse angled triangle hai.

(ii) Sides k aadhar par triangle k types-:

Friends, jaisa ki hum jaante hai ki triangle me 3 sides hote hai. Sides k basis (aadhar) par triangle k 3 types hote hai-:

(a) Equilateral triangle
(b) Isosceles triangle
(c) Scalene triangle

(a) Equilateral triangle-:

Equilateral triangle ko hindi me "sambaahu tribhuj" (समबाहु त्रिभुज) kahate hai.

Defination of equilateral triangle-:

Wo triangle jiska sabhi 3 sides equal  ho aor sabhi 3 angles 60°- 60° k ho , to aise triangle ko "equilateral triangle" kahate hai.

For example-:

Upper diye triangle me,

Sides-           AB = BC = CA

Angles-      /_A = /_B = /_C = 60°

Isliye upper diya ∆ABC ek equilateral triangle hai.

(b) Isosceles triangle-:

Isosceles triangle ko hindi me " samadvibaahu tribhuj" kahate hai.
Defination of isosceles triangle-:
Wo triangle jisk koi bhi 2 sides equal and inn 2 sides se banaya angle equal  ho. To aise triangle ko "isosceles triangle" kahate hai.
For example-:

∆ABC me ,         AB = BC
      and             /_B = /_C

Isliye diya ∆ABC ek isosceles triangle hai.

(c) Scalene triangle-:

Scalene triangle ko hindi me "vishamabaahu tribhuj"(विषमबाहु त्रिभुज) kahate hai.

Defination of scalene triangle-:

Wo triangle jisk sabhi  3 sides equal nhi  ho , to aise triangle ko " scalene triangle" kahate hai.

For example-:

∆ABC me ,

Sides -:   AB , BC and CA equal nhi hai. Isliye ye ∆ABC ek scalene triangle hai.
