Question

Application of congruence and similarity

Answer 1

What is the error in Jake's proof?
He assumes that triangle DPC has all sides equal.

He assumes that triangle APB is an equilateral triangle.

He assumes that the triangles are congruent by the SAS postulate.

He assumes that angle ADC measures 90°.

Answer 2

@ganeshie8 I think the answer is B am I correct ?

Answer 3

Correct ! APB was not given as equilateral triangle, so he needs to prove that APB is equilateral if he wants to using it.
