the triangles are congruent by the sss congruence theorem. which rigid transformation(s) can nap abc onto fed?

a) rotation, then translation

b) reflection, then dilation

c) rotation, then reflection

d) reflection, then translation

i think it’s d, is that right?

You're correct, reflection is when you flip it over, translation is just moving it.

Answer- D: reflection, then translation

On my Edg 2020 B is reflection, then translation, but this is correct for your Edg 2020 question.

Explanation: Correct on Edg 2020.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

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
