The term ‘related angle’ should be introduced. For example, compare the value of . sin 30° and sin 150° using the unit circle. Students may recall aids related to which quadrants of the unit circle contain positive results for sin θ , cos θ and tan θ could be used such as CAST or mnemonics like All Stations To Central (ASTC).

Central Angle = 60 degrees. Area of the sector = 6.41 cm2 . Arc length = 3.67 cm. Describe a formula that might be used to find arc length. Use the appropriate vocabulary (circumference, central angle, etc.) to explain what variables are used in the calculations. N = the measure of the central angle; r = radius of the circle

Remember that a circle graph displays information as parts of a whole and that proper circle graphs use percents to relate the different sectors. A full circle is made up of 360˚. All of the angle measurements (central or sector angles) within the circle must add up to this number. To draw a circle graph, we must. know the number of degrees
