1 Geometry Investigating Angles Drawing an Angle

2 Angles An angle consists of a vertex and two arms. This angle is named XYZ or ZYX X Y Z vertex angle arm

3 Drawing Angles

4 Step 1: To draw an angle, start with one arm of the angle. Example: Draw an angle DEF with a measure of 65° E F

5 Drawing Angles Step 2: Place a protractor on top, with the vertex and base aligning with the vertex and arm of the angle. Example: Draw an angle DEF with a measure of 65° E F

6 Drawing Angles Step 3: Place a mark at 65° on the edge of the protractor. Example: Draw an angle DEF with a measure of 65° E F

7 Drawing Angles Step 4: Remove protractor and draw arm from vertex (E). Label as arm D. Example: Draw an angle DEF with a measure of 65° E F D 65°

8 Drawing Angles Step 1: To draw an angle, start with one arm of the angle. Example: Draw an angle RST with a measure of 123° S R

9 Drawing Angles Step 2: Place a protractor on top, with the vertex and base aligning with the vertex and arm of the angle. Example: Draw an angle RST with a measure of 123° S R

10 Drawing Angles Step 3: Place a mark at 123° on the edge of the protractor. Example: Draw an angle RST with a measure of 123° S R

11 Drawing Angles Step 4: Remove protractor and draw arm from vertex (S). Label as arm T. Example: Draw an angle RST with a measure of 123° R S T 123°
