Jermaine knows that Triangle Q R S and Triangle F G H each have two sides that are 9 mm long. What statement best describes the two triangles?

C)The two triangles may be congruent, but additional measurements are needed.

Step-by-step explanation:Not 100% sure

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

i believe the answer is d.

hope it you! : d
