Question

What is true about ZQRT? Select two options.

Om ZQRT = 90°
-
Om ZQRT = m ZSRT
QRT = STQ
-
Om ZQRT = 2*m ZRTQ
OZQRT = ZRTO

Answer 1

choice one and choice two

Explanation:

Here is a rule: If the bisector of an angle in a triangle is perpendicular to the opposite side, the triangle is isosceles.

Since the question states that QST is isosceles, and that RT is an angle bisector, we can safely assume that RT is perpendicular to SQ.

All perpendicular line segments form right angles, so ∠QRT and ∠SRT are right angles

All right angles are equal to 90°

So, ∠QRT is 90°

All right are congruent, so ∠QRT ≅ ∠SRT

So the answer to this question is choice one and choice two
