1.	Can a triangle together have the following angles ?(i) 55°, 55° and 80°(ii) 33°, 74° and 73°(iii) 85°, 95° and 22°.
Answer» (i) Sum of all angles of a triangle = 180° Here, 55° + 55° + 80° = 180° 190° ≠ 180° No. (ii) 33°+ 74°+ 73°= 180° 180°= 180° Yes. (iii) 85° + 95° + 22° = 180° 202° ≠ 180° No.

Answer»

(i) Sum of all angles of a triangle = 180°

Here, 55° + 55° + 80° = 180°

190° ≠ 180°

No.

(ii) 33°+ 74°+ 73°= 180°

180°= 180°

Yes.

(iii) 85° + 95° + 22° = 180°

202° ≠ 180°

No.
