finding missing angles
We need a new theory
Although you don’t know what happened, if you can come up with
some imaginative suggestions about what might have happened,
you can test them by working out whether the angles add up, just
like when you proved that Benny couldn’t have shot Micky.
Right. So now’s the time to start
guessing? Maybe some aliens came
down and shot Micky? This is stupid.
It’s not just a matter of guessing.
You can use the statement Benny gave and all the relevant
information on the crime scene sketch to guide you. Our
points, lines, and angles are still as true as ever.
Statement by Benny on
release from custody
What I tried to tell them
when I was arrested is that
I don’t even own a gun! But
there was this other guy
there, Charlie, inside the
building. I think he took
a shot at me. I heard a
gunshot and breaking glass
so I ducked. The bullet hit
the car that was parked
behind me—it sped away. I
don’t know how Micky ended
up shot, but at least you
know it wasn’t me!
Read over Benny’s statement. Using the sketch on the left page,
or a blank sheet of paper, can you come up with a new idea
about how Micky got shot?
(You can assume it didn’t involve aliens.)
