# Thread: House of Mirrors -- find the angle

1. ## House of Mirrors -- find the angle

The angle at which light strikes a mirror is equal in measure to the angle at which it is reflected. In the Hall of Mirror below, what is the measure of the angle indicated by the question mark?

Did you see this quickly or take the long, find several angles, approach?

3. Actually, finding all the angels went fast as long as you remember 2 rules of angles for different shapes.

That was a good one KW!

4. I didn't see any pins for angels to dance on in the diagram.

5. Here's an "explanation" with some pins...

6. Oops, my ability to see spelling errors out of the corner of my eye has tripped me up again. I was actually referring to Maud's misspelling of angles as angels, hence the reference to pins and dancing. I can be very obscure....

7. Actually, I suspect Maud DID find angels when calculating all of the angles. Maud quickly came up with the correct solution that I can see Maud doing the dancing. Well, not really...

Maud will chime in soon, I'm sure.

8. My head was in the clouds with this puzzle. Maybe that's why I was seeing angels. Thanks for the in-depth explantion KW

9. The angle is 70 degrees.
