Step-by-step explanation:

Given: AC is a bisector of ∠BCD

           DC ⊥ AD

           BC ⊥ AB

To prove : BC ≅ Dc

                       Statements                        Reasons

1). AC bisects ∠BCD                       1). Given

2)∠ACB ≅ ∠ACD                           2). AC is a bisector of ∠BCD

3). DC ⊥ AD                                    3). Given

4). m∠ADC = 90°                            4). DC is perpendicular to AD

5). BC ⊥ AB                                     5). Given

6). m∠ABC = 90°                            6). BC is perpendicular to AB

7). ∠ABC ≅ ∠ADC                          7). Right angles are congruent

8). AC ≅ AC                                    8). Reflexive property

9). ΔABC ≅ ΔADC                          9). AL property of congruence

10). BC ≅ DC                                  10). CPCTC

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
