Question

HELP PLEASE GIVING MEDAL TO BEST ANSwer :D

Answer 1

Triangle DEF has been dilated to form triangle D'E'F'. What is the least amount of information needed to determine if the two triangles are similar? (5 points)

Angle F=F', angle E=E', and segments EC and E'C' are congruent.
Segment EC=E'C', segment DF=D'F', and angles E and E' are congruent.
Angles E and E' are congruent and angles F and F' are congruent.
Segments DF and D'F' are congruent and segments EF and E'F' are congruent.

Answer 2

to figure out if two shapes are simiar
you only need to know if 2 angles are congruent or not
from that info we know that the third angle must be congruent as well making the two shapes similar
what do you think is the answer then?

Answer 3

c?

Answer 4

if any 'two sets of angle pairs' are congruent, then triangles are similar.

Answer 5

this is called Angle Angle similarity

Answer 6

c. Angles E and E' are congruent and angles F and F' are congruent. is sufficient to conclude the triangles are similar

Answer 7

yes, you are correct :)

Answer 8

thanks
