For questions 3-6, determine if the statement is true or false.
- For an angle^6 ABC,Cis the vertex.
- For an angle^6 ABC,ABandBCare the sides.
- Themin front ofm^6 ABCmeans measure.
- The Angle Addition Postulate says that an angle is equal to the sum of the smaller angles around it.
For 7-12, draw the angle with the given degree, using a protractor and a ruler.
- 55◦
- 92◦
- 178◦
- 5◦
- 120◦
- 73◦
For 13-16, use a protractor to determine the measure of each angle.
