A Jefferson County teacher picked the wrong example when he used assassinating President Barack Obama as a way to teach angles to his geometry students.
Someone alerted authorities and the Corner High School math teacher was questioned by the Secret Service, but was not taken into custody or charged with any crime.
The teacher was apparently teaching his geometry students about parallel lines and angles, officials said. He used the example of where to stand and aim if shooting Obama.
"He was talking about angles and said, 'If you're in this building, you would need to take this angle to shoot the president,' " said Joseph Brown, a senior in the geometry class.
"We are going to have a long conversation with him about what's appropriate," said Superintendent Phil Hammonds. "It was extremely poor judgment on his part, and a poor choice of words."
