Gettin' shmoopy with it...

00:05

In the following diagram, lines A and B are

00:07

parallel. Line C is perpendicular. Angle 4 measures 105°.

00:12

What does Angle 2 measure?

00:13

And here are the potential answers...

00:17

OK so what is this question asking?

00:19

Yeah -- line D... and the measurement of Angle 4... are total decoys.

00:23

All we need to recognize is that, because C is perpendicular to A...

00:28

...All of the angles located at the intersection of those two lines will be 90 degrees.

00:34

In fact, that little square thingy tells us the same thing... that we're dealing with right angles.

00:39

So our answer is C.
