Question

Which of these angles can form a triangle?
(a) 30°, 60°, 80°
(b) 0°, 90°, 90°
(C) 80", 20°, 80°
(d ) 90°, 60°, 60°​

Answer 1

Step-by-step explanation:

Sum of the angles of triangle is 180degrees.

a)90+30+50=170 degrees

Hence it is not a triangle

b)40+40+100=180 degree,

Hence it is a triangle

c)50+60+70=180degrees

Hence it is a triangle

d)20+30+40=90 degrees ,

Hence it is not a triangle.
