Question 9
The minute hand moves from 12 to 9. Each number on a clock is \(30^{\circ}\) from the next. How many degrees did it turn?
Question 10
Which measure could be an obtuse angle?

Remember
  • An angle has two rays and one shared endpoint called the vertex.
  • A full circle is 360 degrees, a half turn is 180 degrees, and a quarter turn is 90 degrees.
  • A one-degree angle turns through 1/360 of a circle.
  • Acute angles are less than 90 degrees, right angles are exactly 90 degrees, and obtuse angles are greater than 90 degrees.
  • If an angle is split into parts, the whole angle is the sum of the parts.
