Isosceles

3. linda18

is it right , obtuse, acute

4. linda18

ANYONE

5. jiteshmeghwal9

acute

6. jiteshmeghwal9

it's acute as every angle is less than 90

7. apoorvk

Sum of all angles of a triangle equals 180\(^o\). So, we have an equation! \[2x +2x +4x = 180\] What's 'x'?

8. jiteshmeghwal9

Solve 4x+2x+2x-180

9. linda18

22.5

10. apoorvk

yeah so what are the angles 2x, 2x, and 4x?

11. linda18

ACUTE

12. jiteshmeghwal9

Put x

13. nishika17

its a right angled triangle

14. nishika17

value of x= 22.5 and you get 45,45,90

15. nishika17

by puttin 2x,2x,4x

16. linda18

YEA SO IT A RIGHT

17. apoorvk

exactly!

THANK YOU

I HAVE ONE MORE QUESTION

20. apoorvk

Also you could do it this way - if you remember that it's only in a right angle where the sum of two angles add upto the third --> 2x + 2x = 4x here. so, a right triangle!

21. apoorvk

Yes, please post it in a fresh thread after closing this question! :]
