Copy an Angle
1) Start by using the Circle with Center through Point tool
to create a circle with a center at point B, making sure it intersects both sides of angle ABC.
2) Use the Intersect tool
to mark the intersections of that circle with the sides of angle ABC.
3) Using the Compass tool
, create a circle with a radius the same size as the one you previously made centered at point D. Do this by clicking point B, then one of the intersection points you created, then point D.
4) Use the Intersect tool
to create a point where this new circle intersects ray DF.
5) Use the Compass tool to create a circle with a radius equal to the distance between the two intersection points from angle ABC. Do this by clicking one of those points, then the other. Then click the intersection point you created on ray DF in step 4.
6) Use the Intersect tool to mark the intersection of this circle and the circle you created in step 3.
7) Use the Ray tool
to create a ray from point D through the point you made in step 6.
8) Use the Angle Measure tool
to verify that your new angle is congruent to the original angle. Do this by clicking on the intersection point on ray DF, then point D, then the last intersection point you created.
