Question

I just need feedback to see if I am getting the material, anyone up for checking two questions??

Answer 1

@jim_thompson5910

Answer 2

both are incorrect

Answer 3

are they suppose to be switched?? What did I do wrong??

Answer 4

In the first one, AC is perpendicular to BD

AC also cuts BD into two equal parts

Answer 5

so would it be perpendicular bisector, but i thought that angle bisector starts at a vertex and cuts the triangle to make both sides congruent.

Answer 6

we don't know if angle DAB is cut in half or not

so we can't say AC is an angle bisector

Answer 7

Oh that make sense, so does that apply to the perpendicular bisector as well?

Answer 8

What do you mean?

Answer 9

Im so confused :(

Answer 10

Where are you stuck?

Answer 11

Im confused on the fact that its not an angle bisector.

And how it could be any of the other answer choices.

Answer 12

Say we have this angle

Answer 13

Now if we cut it in half



we create the angle bisector

Answer 14

we don't know if we've cut the angle in half in that first problem

so we can't say for sure it's an angle bisector

Answer 15

Oh, I get it so, Would it be a perpendicular bisector because we know that BC is congruent to DC, because doesn't a perpendicular bisector create congruent sides?

Answer 16

yep, it cuts BD in half to create two congruent pieces

Answer 17

AC is also perpendicular to BD

Answer 18

So the answer would be perpendicular bisector because it creates two congruent pieces,

Answer 19

So whenever a problem states that two sides are perpendicular and names other congruent sides then would it automatically be perpendicular bisector

Answer 20

It might help to view it like this

here is segment BD
