Question

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?

Answer 1

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

Answer 7

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

Answer 8

this is called Angle Angle similarity

Answer 9

c. Angles E and E' are congruent and angles F and F' are congruent.

is sufficient to conclude the triangles are similar

Answer 10

if that makes any sense.. .
