Question

Are the following triangles possible with the given angles?
(i)88°, 42°, 120°
(ii) 50° 50°, 50°
(iii) 40°, 50,° 80°
(iv) 48°, 62°, 70°
(v) 35°,95°, 90°​

Answer 1

Answer:

( iv ) 48° , 62° , 70°

According to the Angle Sum Property we can construct a triangle from the above measure as their total is 180° .

48° + 62° + 70° = 180°

Answer 2

Answer:

(iv) 48°,50°,80° are possible

and (i), (ii), (iii) and (v) are not possible
