Well, the question has it's answr itself there but I was thinking that since one angle of a Right angled triangle is 90 degrees

3. mathslover

So, next angle (let it be $$\angle A$$ ) $$\angle A < 90$$

4. mathslover

Am I right here?

5. mathslover

@hartnn @helder_edwin ?

6. hartnn

which part r u talking about ?a,b or c ?

7. hartnn

and yes, any other angle, in right triangle is less than 90

8. mathslover

the two angles which are NOT equal to 90 degrees.

9. helder_edwin

both angles other than the right one would have measure less than 90º

Right so, we have : $$\angle A \space \space \text{And} \space \space\angle B <90$$

12. mathslover

I was just freshing up my mind so sorry for silly question.

13. hartnn

yup.

14. hartnn

due to property that A+B+90=180 so u also get A+B=90

15. mathslover

Right

16. hartnn

next question ;)

17. mathslover

It would not be easy one @hartnn ... r u ready?

18. hartnn

hell yes!

Then OK, wait for a minute,
