What is the correct congruency statement for the triangles shown? ΔACB ≅ ΔFED ΔBAC ≅ ΔDFE ΔCAB ≅ ΔFDE ΔCBA ≅ ΔEFD

OpenStudy (mathlegend):

Try mentally flipping the triangles. Which angle is colored in the picture?

OpenStudy (anonymous):

@MathLegend D & A

OpenStudy (mathlegend):

Good, so now we know that in the statement first that D & A must match up. So that is only seen in the last two. So it out of the last two.

OpenStudy (mathlegend):

So now which two segments(Sides) have two hash marks?

OpenStudy (anonymous):

@MathLegend Alright! And they're sides DF and AB

OpenStudy (mathlegend):

Good so now F & B must be lined up as well

OpenStudy (mathlegend):

So which one has D & A lined up then has F & B lined up in the congruent statement?

OpenStudy (anonymous):

@MathLegend The last one?

OpenStudy (mathlegend):

Yup

OpenStudy (anonymous):

@MathLegend Ohhh that makes it so much simpler! I understand, find what matches up in the picture and then see how they match up as answer choices. Thank you so much :)

OpenStudy (mathlegend):

No problem :)
