Question

Check Proof
Given: AB and CD bisect each other
Prove: AC = BD and AC is perpendicular to BD

Answer 1

Statements:
1. AB and CD bisect each other
2. AO = BO and CO = DO
3. Angles AOC = Angle BOD
4. ?
5.?
6. Triangle AOC is congruent to Triangle BOD

Reasons:
1. Given
2. Def of segment bisectors
3. ?
4. ?
5. ?
6. SAS

Answer 2

Reason 3 = vertically opposite angles.

Answer 3

# 4is triangle AOC and BOD are congruent by sas

Is #2 right?

And what is statement and reason for number 5?

Answer 4

Number 2 is right.

Answer 5

I'm not sure about 5th. :/

Answer 6

I know that part of it is AC = BD but there is an angle just not sure what it is maybe... angle

Statements:
1. AB and CD bisect each other
2. AO = BO and CO = DO
3. Angles AOC = Angle BOD
4. Triangles AOC and BOD are congruent to each other
5.?
6. AC is perpendicular to BD

Reasons:
1. Given
2. Def of segment bisectors
3. Vertically Opp angles
4. SAS
5. ?
6. When 2 st. lines are cut by a traversal if a pair of alternate interior angles are = the 2 st. lines are perpendicular

Answer 7

How about using SSS property?

Answer 8

for # 4?

Answer 9

5.

Answer 10

not sure that would work

Answer 11

would it?

Answer 12

I'm not sure either. xD

Answer 13
