Triangle qst is isosceles, and bisects t. what is true about qrt? check all that apply. qrt = 90°
qrt = srt
qrt stq
qrt = 2*rtq
qrt rtq

Given that triangle QST is isosceles, and bisects T, the line bisecting T also bisects QS.

A line that bisects the other angle of an isosceles triangle, bisects the opposite line at right angle. Therefore, since triangle QST is isosceles, and bisects T, the line bisecting T bisects QS at R and then QRT = SRT = 90 degrees.

QRT cannot be equal to STQ since an isosceles triangle does not have a right angle as QRT is a right angle.

2*RTQ is equivalent to STQ, and it has been established that QRT is not equal to STQ. Thus QRT is not equal to 2*RTQ.

QRT cannot be equal to RTQ since an isosceles triangle does not have a right angle as QRT is a right angle.

Therefore, the true statements about QRT is QRT = SRT.
