Write a paragraph or two column proof Given ABCD is a dart with segment AB segment AD and segment BC segment DC Prove Angle B Angle D class=

Respuesta :

AB = AD and BC = DC are given. Furthermore, we can see that AC = AC by the reflexive property. We have three pairs of congruent corresponding sides, which allows us to use the SSS congruence theorem. From that, we would use CPCTC to conclude that angle B is congruent to angle D.

CPCTC = corresponding parts of congruent triangles are congruent.
