Triangle MNO is dilated to form new triangle PQR. If angle O is congruent to angle R, what other information will prove that the two triangles are similar?

OpenStudy (anonymous):

A) Side ON is congruent to side RQ. B) Angle N is congruent to angle Q. C) Side MN is congruent to side PQ. D) Angle M is congruent to angle Q. Is it C or B?

OpenStudy (linyu):

you need two congruent angles, or side and side to prove similarity i think

OpenStudy (linyu):

side, angle, side. sorry

OpenStudy (linyu):

AAA (angle angle angle) All three pairs of corresponding angles are the same. See Similar Triangles AAA. SSS in same proportion (side side side) All three pairs of corresponding sides are in the same proportion See Similar Triangles SSS. SAS (side angle side) Two pairs of sides in the same proportion and the included angle equal. See Similar Triangles SAS.

OpenStudy (nikato):

U would just need another angle to prove they r similar

OpenStudy (anonymous):

So its B?

OpenStudy (nikato):

Correct

OpenStudy (linyu):

as long as all the angles are equal, the triangles will be similar.

OpenStudy (anonymous):

I knew it ! Thanks :)

OpenStudy (nikato):

It won't be D becuz of the way it's written mnO and pqR N and Q are in same "positions" but M and Q arent

And ur welcome!
