Describe how to use a protractor and straightedge to draw a 130° angle. then describe how to
bisect the angle using a compass.
a)
use the straightedge to draw a ray center the protractor at the endpoint on the left of the ray
use the outside scale of the protractor to mark 130. use the straightedge to draw another
ray between the endpoint on the left of the ray and the mark at 130
place the compass point at the vertex of the 130-angle. draw an arc that intersects both sides
of the angle. use the straightedge to draw the line segment connecting the points where the arc
intersects each side of the ray.
b)
use the straightedge to draw a ray. center the protractor at the endpoint on the left of the ray,
use the inside scale of the protractor to mark 130. use the straightedge to draw another
ray between the endpoint on the left of the ray and the mark at 130
place the compass point at the vertex of the 130-angle. draw an arc that intersects both sides
