Question

Triangle STU has been dilated to form triangle PQR. What is the least amount of information needed to prove the two triangles are similar? (5 points)
Question 4 options:
1) Two pairs of corresponding angles and one pair of corresponding sides
2) Two pairs of corresponding angles
3) Two pairs of corresponding sides and one pair of corresponding angles
4) Two pairs of corresponding sides
*Help please

Answer 1

Similar means they don't have to be the same size, therefore, you can 2 pairs of corresponding angles and that only leaves 1 other measurement for the last angle.

Because there is 180 degrees in the angles of a triangle, let's say the first two are both 40 degrees. 180 (total degrees in triangle interior) -40 -40 =100. 100 degrees would be the last corner. But that was just an example, of course.

Answer 2

I made a typo in the first line, sorry. Similiar mean they don't have to be the same size, so you can HAVE 2 pairs of corresponding angles.

Did that answer your question?
