6. Stretch Your Thinking Hannah says that when the
hands on a clock show 9:30, the angle is 90˚. Jennie
says the angle is obtuse. Who is correct? Explain.
Make a drawing to show which girl is correct.
Jennie is correct. Possible answer: when the
hands on a clock show 9:30, the minute hand
will be on the 6 and the hour hand will be
half way between the 9 and 10. This angle has
a measure greater than 90°, so it is obtuse.
The measure of ∠BCE is 125˚.
Check students’
drawings. Clocks
should show 9:30.
