Identify the angles of rotational symmetry and point symmetry for the figure. If the figure does not have rotational symmetry, select "no rotational symmetry". If the figure does not have point symmetry, select "no point symmetry". Note: You can duplicate angles.

EASY POINT R

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

correct answer:

b.(19,-2)
