Too less information, too easy to solve.

Geometry Level 2

You are given that $\text{AC}$ is parallel to $\text{BD}$ and this figure:

Is it true that the red angles are equal?

This is part of the series: " It's easy, believe me! "

It depends on the measurement of

\widehat{\text{ABC}}

. No, it is false. I don't even know. (This is not the right answer.) Yes, it is true.

The 2 triangles with the red angle at one end are similar via SAS similarity, so the 2 red angles are similar.
