Question

State if it is possible to have triangles whose angle measurements are as follows :-
i)45 degree,60 degree,73 degree.
ii)48 degree,60 degree,72 degree .
iii)65 degree,65 degree,50 degree .
iv) 90degree,90 degree,10 degree.
answer all these......​

Answer 1

Answer:

1 and 4 is not possible because sum of their interior angle is not 180 degree while 2 and 3 are possible.

Answer 2

Answer: c

Step-by-step explanation: a triangle is defined as a figure whose internal angles has a sum of 180 degrees. Except c, none options make a sum of 180 degrees and therefore are not triangle. On the other side, option c makes a sum of 180 degrees and hence, it is a triangle.
