Question

PLZ HELP ME

Select from the drop-down menu to correctly complete the statement. There is enough information to conclude that the two triangles are _______ if x = 48.
A. Similar
B. Not Similar

Answer 1

b, not similar.

Explanation:

the angle in triangle 1, is 40.

the same angle in triangle 2, is 48.

therefore, they are not similar, despite both having right angles.

also i just took the quiz and put A. it was the only wrong answer.

Answer 2

You need at least 2 congruent angles , or 3 proportional sides , or 2 proportional sides and 1 congruent angle to prove that 2 triangles are similar.
I presume that there should be a picture attached to this question , but if you only have 1 side in proportion ( x ) , you cannot prove the similarity of two triangles.

But if there already were two proportional sides or 1 proportional side and one congruent angle , you can prove they are similar if x = 48

Hope it helps
