Question

5. IF THE ANGLES OF A TRIANGLE ARE IN THE RATIO 1:2:3 , FIND THE ANGLES . CLASSIFY THE TRIANGLE IN TWO DIFFERENT WAYS.

Answer 1

$\bold\red{Let\:the\:sides\:be=1x,2x,3x}$

$\bold\orange{1x+2x+3x=180(angle\:sum\:property)}$

$\bold\green{6x=180}$

$\bold\blue{x=30}$

So, sides would be⤵

x= 30°

2x= 60°

3x= 90°

Answer 2

Let the angle shoud be x, 2x, 3x
By angle sum property
x + 2x + 3x = 180

6x = 180
x = 180/6
x = 30

2x = 2* 30 = 60

3x = 3* 30 = 90


Angle be 30, 60, 90
Triangle is right angle triangle or isoscele triangle
