Question

Andrew draws triangle ABC. He then constructs a perpendicular bisector from vertex A that intersects side BC at point D. What can Andrew conclude, based on his drawing?
AB = BC
BD = DC
AD = BC
AC = BC

Answer 1

Answer:

BD = DC

Step-by-step explanation:

A perpendicular bisector is a line segment that goes form a vertex to its opposite side. The important characteristic is that a perpendicular bisector intersects the opposide at the mid point and with a right angle, that's why is called perpendicular and bisector.

So, Andrew can conclude that side BC is divide equally, that is, BD = DC.

Therefore, the right answer is the second choice.
