Question

if yes then why if no then why

please give the correct answer
i will mark as brainlist ​​

Answer 1

Answer:

3i) 40+70+80=190

no we cannot draw a triangle with these measures since we know the sum of all interior angles must be 180°

3ii)yes a triangle with such measures can be drawn. it will be a scalene triangle

3iii) yes a triangle with such measures can ve drawn . it will be isosceles triangle since two sides are equal.

Answer 2

Answer:

for 1st 40,70,80

40+70+80=190

so it is not possible because of angle sum theory

for second, 16,7,8

using Pythagoras theorem: 7^2 + 8^2 = 16^2

49+64=256

113 is not equal to 256

so false

for third 2.5,3.5,2.5

using Pythagoras theorem: 2.5^2 + 2.5^2=3.5^5

6.25+6.25=12.25

12.5 is not equal to 12.25

so false
