Question

10th grade geometry
Select statements that are true about angles on diagram

Answer 1

B, C

Explanation:

The only statements that must be true are ones that describe the markings on the diagram:

NO as an angle bisector

N is the vertex of a pair of congruent angles

_____

The only other fact that must be true is that segments on the left side of the diagram are proportional to those (corresponding) on the right. (This is a property of the angle bisector.) There is nothing that says the sides must be equal, or that the triangle is isosceles.
