Trisecting a line segment by using only a straightedge and compass was proven impossible by advanced algebra.

True or False

The correct answer is True.

That is, it is impossible according to the mathematical proof put forward by Pierre Wantzel in 1837, to trisect a line segment by using only a straight edge and a compass.

What is possible however is the trisection of a right angle.  

It is also possible to trisection other arbitrary angles using other tools besides a straight edge and a compass.

Trisection refers to the division of a quantity or a number into three equal parts. Angle trisection refers to the construction of an angle equal to three arbitrary angles that are equal to each other.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
