Name the postulate, if possible, that makes the triangles congruent.

• SSS

• SAS

• Not Possible

What is the missing piece of information required to prove these triangles congruent?

• QY ≅ QY

• NY ≅ PY

• ∠N ≅ ∠P

• QY is the perpendicular bisector

Name the postulate, if possible, that makes the triangles congruent.

• SSS

• SAS

• Not Possible

What additional information is required to prove the two triangles are congruent by SSS? Choose all correct choices.

• A)

• B)

• C)

• D)

Fill in the missing pieces of the proof.

• Transitive Property, SAS(Side-Angle-Side)

• Reflexive Property, SAS(Side-Angle-Side)

• Reflexive Property, Vertical Angles Thm.

• Transitive Property, SSS(Side-Side-Side)

What additional information can we conclude from the given and why?

• ∠ADB and ∠ADC are right angles because AD goes straight down.

• ∠B≅∠C because the triangle is isosceles

• ∠BAD≅∠CAD because they look the same

• None of the above

What are the 2 missing pieces of information?

• Transitive Property, SAS(Side-Angle-Side)

• Reflexive Property, SAS(Side-Angle-Side)

• Transitive Property, SSS(Side-Side-Side)

• Reflexive Property, SSS(Side-Side-Side)
