Question

Given: AC Congruent BD, AD Congruent BC

Which could be used to prove TriangleDCA Congruent TriangleCDB?

Answer 1

f (SAS) If 2 sides and the angle between them in one triangle
are congruent to 2 sides and the angle between them in another
triangle, then the triangles are congruent.
g (ASA) If 2 angles and the side between them of one triangle
are congruent to 2 angles and the side between them of another
triangle, then the triangles are congruent.
h (AAS) If 2 angles and a side not between them are congruent
to 2 angles and a side not between them of another triangle,
then the triangles are congruent.
j (SSS) If 3 sides of one triangle are congruent to 3 sides
of another triangle, then the triangles are congruent.

Answer 3

well, you were already given two pairs of congruent sides right?
so then g and h wouldn't make sense...

Answer 4

Yep those are eliminated

Answer 5

J?

Answer 6

yes :) because you can get DC = DC by reflexive property of equality ^_^

Answer 7

Yay thanks :) @jigglypuff314
