Name the types of following triangles on the basis of given angles (i

1.	Name the types of following triangles on the basis of given angles (i) 105°, 46°, 29° (ii) 60°, 60°, 60° (iii) 57°, 33°, 90°
Answer» Types of triangles on the basis of angles (i) 1050 ≠ 46° ≠ 29°, 105° > 90° Obtuse – angled triangle (ii) 60° = 60° = 60°, 60° < 90° Acute – angled triangle (iii) 57° ≠ 33° ≠ 90° Right – angled triangle.

Name the types of following triangles on the basis of given angles (i) 105°, 46°, 29° (ii) 60°, 60°, 60° (iii) 57°, 33°, 90°

Answer»

Types of triangles on the basis of angles

(i) 1050 ≠ 46° ≠ 29°, 105° > 90° Obtuse – angled triangle

(ii) 60° = 60° = 60°, 60° < 90° Acute – angled triangle

(iii) 57° ≠ 33° ≠ 90° Right – angled triangle.
