Question

can a triangle be constructed with angle 45 degree 64 degree and 72 degree ?
​

Answer 1

Answer:

No

Because sum of all angles of triangle is 180 but here it is 181 which is greater than 180

Answer 2

Answer:

the sum of the angles of a triangle should always be 180°

now.

64°+72°+45° =181°

so construction with these measures isn't possible you can subtract 1° from 45 to make it a 180° .

hope you get the answer.
