Question

Как спомощью циркуля и линейки построить угол равный 22,5 градусам

Answer 1

Нужно построить две перпендикулярные прямые, образуется угол 90 градусов. Делишь этот угол пополам (это одно из основных построений, надеюсь ты знаешь, как его делать), получается угол 45 градусов. Угол в 45 градусов еще раз делишь пополам, получается угол в 22,5 градуса. 

Answer 2

Constructing an Angle Equal to 22.5 Degrees Using a Compass and Ruler

To construct an angle equal to 22.5 degrees using a compass and ruler, follow these steps:

1. Draw a Ray: - Use a ruler to draw a ray (straight line) on a piece of paper. This will serve as the initial side of the angle.

2. Place the Compass on the Ray: - Place the pointed end of the compass on the vertex of the angle (the point where the two sides of the angle will meet).

3. Draw an Arc: - Without changing the width, draw an arc that intersects the ray. This will create a point of intersection.

4. Adjust the Compass: - Without changing the width, place the pointed end of the compass on the point of intersection created in the previous step.

5. Draw Another Arc: - Draw another arc that intersects the first arc.

6. Draw the Angle: - Use a ruler to draw a line from the vertex to the point where the two arcs intersect. This line will form the second side of the angle.

By following these steps, you will have constructed an angle equal to 22.5 degrees using a compass and ruler.
