The measures of three angles of a triangle are in the ratio 1 : 2 : 3 Then the triangle is.
1 Right angled
2 Equilateral
3 Isosceles
4 Obtuse angled
Explanation:
Right angled Angles are in the ratio = 1 : 2: 3 Let the angles be x, 2x, 3x Sum of angles = 180 x + 2x + 3x = 180 6x = 180 x = 30\(^{1}\) Hence, the angles are 30\(^{1}\), 60\(^{1}\), 90\(^{1}\) The triangle is a right angled triangle.
