question

In the diagram, KL ≅ NR and JL ≅ MR. What additional information is needed to show ΔJKL ≅ ΔMNR by SAS?

answer

∠K ≅ ∠N

question

If bisects ∠ACD, what additional information could be used to prove ΔABC ≅ ΔDBC using SAS? Select three options.

answer

m∠ABC = 125° and AB ≅ DB, ΔABD is isosceles with base AD, CD = 52 cm

question

If VX = WZ = 40 cm and m∠ZVX = m∠XWZ = 22°, can ΔVZX and ΔWXZ be proven congruent by SAS? Why or why not?

answer

No, the sides of the triangles intersect.

question

Triangles RQS and NTV have the following characteristics:• Right angles at ∠Q and ∠T • RQ ≅ NT

answer

No, it is not possible for the triangles to be congruent.
