What additional information is required to prove the two triangles are congruent by SSS?
A)
B)
C)
D)
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
