What additional information is needed to prove the triangles are congruent by the sas postulate

Step-by-step explanation:

SAS congruence postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.    

We can see from our given graph that triangle ABD is divided in two smaller triangles ACB and ACD.  

We have been given that side BC equals to side DC. We can see that in triangles ACB and ACD side AC equals to itself.  

In order to triangles ACB and ACD be congruent by SAS postulate measure of angle ACB  and ACD must be equal.      

We can see that angle ACB  and angle ACD form an linear pair, So

If we are given that AC is perpendicular to BD then measure of ACB will be equal to ACD as a perpendicular meets a line at a right angle.

Therefore, the additional information that will prove the triangles ACB and ACD congruent by SAS postulate is .

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
