The figure below shows two triangles that were constructed using a compass and straightedge. Ryan used the SSS postulate to prove that triangle ABC is congruent to triangle DEF. Which of these steps would Ryan have likely performed to prove that the two triangles are congruent by the SSS postulate?

Place the compass on A and set the width to side AC. Without changing the width place the compass on C and draw an arc that crosses CA at B. Place the compass on A and set the width to side AC. Without changing the width place the compass on D and draw an arc that crosses DF at F. Place the compass on A and draw an arc to cross side AC at X and side AB at Y. Without changing the width draw a similar arc from point D. Place the compass on A and draw an arc to cut side AC at X and side AB at Y. Place the compass on X and set the width of the compass to segment XY.

my weakness is geometry

OpenStudy (precal):

This is a construction, I don't even remember learning this at all. This is OLD SCHOOL

OpenStudy (precal):

Let me look on line to see if I can find anything

actually i just cant choose betweem the 1st and 2nd ones

SSS means proving that 2 triangles are the same using only the sides. Look at that link, I believe they are also, doing the same using constructions.

oh well thank you for effort

hi precal do you know how to do this ...what is cos30=16/x

OpenStudy (precal):

$\cos(30)=\frac{16}{x}$ is that cosine 30 degrees?

OpenStudy (anonymous):

yes.....
