Question

Given: Angle BAC is a right angle
Angle DEC is a right angle
Line DB bisects line AE
Prove C is the midpoint of line DB

Answer 1

so how do i write this out then

Answer 2

@jannine245 Are you feeding the proof into a computer program? Or, are you solving on paper? I ask because I am wondering if we are limited in the number of steps. I assume that we are writing a 2-column deductive proof. Let me know before I start with the steps.

Answer 3

i am not limited in what i write it is a 2 xolumn proof yes

Answer 4

yes that is it

Answer 5

tyring ot send message not working how will u send me the work if i close it

Answer 6

@jannine245 Read through the steps and see if they seem correct. Also, be sure a typo did not cause the wrong letter to be entered.

You and I will do the reasons but you complete as many as you can.

Answer 7

If you have not studied the theorem: "All right angles are congruent," we may need to add a step or two. No big deal.

Answer 8

ok i am ready to go the first one is give

Answer 9

number 2 they are both right angles so they are congurent and would that be with right angle congruence therom

Answer 10

i closed it

Answer 11

3 is given

Answer 12

4 they are congruent becuase of congruent angles

Answer 13

Statement 3 is not correctly stated in the post or in the proof statements. I will fix it at the end.

Lines do not bisect lines.

A line can bisect a segment because segments have midpoints.
Lines do not have midpoints.

In this case, one segment bisects another segment.

Answer 14

an angle bisector

Answer 15

Reason 4 is definition of segment bisector. You may want to check that in your book. On reason 4, we are talking segments, not angles.

Answer 16

1. Given
2. Right Angle Congruence Theorem
3. Given
4. Definition of Segment Bisector

Answer 17

5. ?

Answer 18

5 verticle angles angles that share a common vertex and whose sides form 2 lines

Answer 19

two angles are vertical angles, then they’re congruent
