Question

It says what is the missing statement in the proof scroll down to see the entire proof given triangle ABC with measure of angle ABC equals 90 and it says prove a AB to the second plus BC to the second equals AC to the second

Answer 1

The reflexive property of congruence states that a line segment, an angle, or a shape is always congruent to itself.

In the figure, we can see that angle BCA is the same angle DCB, then the reflexive property can be applied to them, which means:

`\angle BCA\cong\angle DCB`
