which one of the following set of internal angles of a triangle does not show well condition triangle? 1)20,90,70 2)25,45,110 3)40,125,15 4)35,80,65 & how?
Answers
Answer:
each condition is correct because triangle then only form when sum of each of triangle is 180°
Option 1, option 2, option 3 does not show well condition triangle
Solution:
Given that,
We have to find the set of internal angles of a triangle does not show well condition triangle
A well conditioned triangle is a triangle in which no angle is less than 30 degrees and greater than 120 degrees
From given options,
Option 1
20, 90, 70
20 is less than 30 degrees
This does not fulfill well conditioned triangle
Option 2
25, 45, 110
25 is less than 30 degrees
This does not fulfill well conditioned triangle
Option 3
40 , 125 , 15
15 is less than 30 degrees
This does not fulfill well conditioned triangle
Option 4
35 , 80 , 65
This fulfill well conditioned triangle
