Question

To copy an angle using only a compass and a straightedge, begin by marking the vertex of the new angle. Then draw a ray from the vertex, which will be one of the legs of the new angle. What is the next step in the construction?

Answer 3

um ok

Set the compass width to the vertex of the angle, place the compass needle at any point on the leg of the new angle, and make an arc in the angle's interior. is thi correc

Answer 4

Yep!:D

Answer 5

in plato that answer was wrong!

Answer 6

Step 1: Mark the point that will be the vertex of the new angle, and label it P.

Step 2: Draw a ray from P in any direction, with any length. This ray will be one of the sides of the new angle.

Step 3: Place the compass point on the vertex of the original angle, and adjust the compass width to a convenient size.

Step 4: Use the compass to draw an arc intersecting both rays of the original angle at two points, J and K.

Step 5: Move the compass (without changing the width) to point P, and make an arc intersecting the existing ray of the angle. Mark the intersection point, and label it M.

Step 6: Set the compass point on the original angle at point J, and set its width to the length of line segment JK.

Step 7: Move the compass point to M on the new angle, and draw an arc cutting the previous arc. Mark the intersection point and label it L.

Step 8: Draw a ray from point P through point L. The new angle is a copy of the original angle.
