  11. How To Measure An Angle

  12. 132 1 76 2

  13. 105 3 14 4

  14. How to draw an angle * Start off by drawing a ray. * Line up the vertex to the hole and the side of the angle with the line next to the hole * Follow your ray to zero and then over to the angle measure. Make a mark and then connect it to the vertex.
