What else would need to be congruent to show that abc def by sas?

Option C is correct

Step-by-step explanation:

SAS(Side-Angle-Side) postulates 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 these two triangles are congruent.

As per the statement:

Given:

In triangle ABC and DEF.

   [Side]

  [Angle]

   [Side]

then by SAS postulates we have;

ΔABC≅ΔDEF

Therefore, need to be congruent to show that:  ΔABC≅ΔDEF

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

20
