Question

Построй луч CD. Отметь точки O и M на луче и точки K и B вне луча.

Answer 1

О и М отмечаешь на линии,которую ты начертила,а К и В напиши где-нибудь,но не на линии.

Answer 2

Construction of Ray CD and Marking Points O, M, K, and B

To construct a ray CD and mark points O and M on the ray, as well as points K and B outside the ray, follow these steps:

1. Start with a line segment AB. 2. Place the compass on point A and draw an arc that intersects the line segment AB at point C. 3. Without changing the compass width, place the compass on point C and draw another arc that intersects the previously drawn arc at point D. 4. Draw a line segment through points C and D. This line segment represents the ray CD.

Now, let's mark the points O, M, K, and B:

- Point O: Place the compass on point C and draw an arc that intersects the ray CD. Label the point of intersection as O. - Point M: Place the compass on point C and draw an arc that intersects the ray CD on the opposite side of point O. Label the point of intersection as M. - Point K: Draw a line segment from point C that extends beyond point D. Label the point of intersection with the ray CD as K. - Point B: Draw a line segment from point C that extends beyond point D on the opposite side of point K. Label the point of intersection with the ray CD as B.

The resulting construction should have a ray CD with points O and M on the ray, and points K and B outside the ray.

Please note that the specific lengths and positions of the line segments and arcs may vary depending on the given measurements or instructions.

I hope this helps! Let me know if you have any further questions.
