When proving these triangles similar, what would you write in for the missing reason?

• Math

• Corresponding sides are proportional

• Corresponding sides are congruent

• SSS similarity postulate

Tags

CCSS.HSG.SRT.B.5

What will the last "reason" of this proof be?

• Definition of Midpoint

• Definition of Angle Bisector

• CPCTC

• Reflexive

CCSS.HSG.CO.C.9

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
