Reorder the steps to construct Angle JOB, a copy of Angle A.
g100num [7]

Answer:

The right order is given as follows;

_Draw a ray that will become one of the two rays of the new angle, label OB

_Place your compass point at the vertex of Angle A. Create an arc that intersects both rays of Angle A

_On Angle A, set the compass point on the intersection of the arc and ray and the pencil on the other intersection of the arc and second ray. Lock your compass

_Without changing your compass setting, create an arc from point O that intersects OB. Be sure to make a large arc.

_Place the point of the compass on the intersection of the arc on OB. Mark an arc arc through the large arc created in a previous step. Label the point of intersection of the two arcs point J.

_Construct OJ

Step-by-step explanation:

1) The first step is to draw a line in the location where the angle to be copied is to be constructed

2) The distance of two points on the rays forming the angle to be copied from the vertex are found by drawing an arc from the vertex and setting the compass opening width to the distances between the intersection of the arc and the rays

3) With the set compass width from the step above, an arc is drawn which intersects the constructed first new ray. The arc is made to extend to a large angle to accommodate large angle sizes

4) From the point of intersection of the arc on the new line, another arc is drawn to intersect the previous arc located on the new line construction

5) Join the point intersection of the two arcs on the new construction to the start point of the constructed first new line (the point from which the first arc was constructed to complete the construction of a copy of the angle.
