Question

Начертите треугольник. С помощью транспортира и линейки проведите его биссектрисы

Answer 1

°
у тебя транспортир есть?

на полукруге градусы, на прямой линии есть черточка (ризка).

прикладываешь прямую транспортира  к одной стороне угла треугольника, чтобы ризка совпала с вершиной угла, тогда вторая сторона угла укажет на полукруге траспортира градусы. например получилось 58°.

 "биссектриса делит угол пополам", значит 58/2=29°

 замечаешь это на транспортире (примерно!! ), и отмечаешь на рисунке. 

линейкой чертишь линию из этого угла  через эту отметку ДО ДРУГОЙ СТОРОНЫ ТРЕУГОЛЬНИКА. биссектриса готова.

то же самое с двумя другими углами.

Answer 2

Drawing a Triangle and Bisecting it

To draw a triangle and bisect it using a protractor and ruler, follow these steps:

1. Start by drawing a line segment using a ruler. This will be one side of the triangle. Let's call it side AB.

2. Place the protractor on point A and align the baseline of the protractor with side AB. Make sure the center of the protractor is on point A.

3. Look at the protractor and find the angle measurement you want for the triangle. For example, if you want a 60-degree angle, locate the 60-degree mark on the protractor.

4. With the protractor still in place, draw an arc from point A towards the interior of the triangle.

5. Without moving the protractor, place the ruler on point A and align it with the arc you just drew.

6. Draw a line segment from point A to where the ruler intersects side AB. This will be side AC of the triangle.

7. Now, place the protractor on point C and align the baseline with side AC.

8. Find the angle measurement that is half of the angle you used earlier. For example, if you used a 60-degree angle, find the 30-degree mark on the protractor.

9. Draw an arc from point C towards the interior of the triangle.

10. Without moving the protractor, place the ruler on point C and align it with the arc.

11. Draw a line segment from point C to where the ruler intersects side AB. This will be the bisector of angle BAC.

12. Finally, draw the remaining side of the triangle by connecting points B and C.

You have now successfully drawn a triangle and bisected it using a protractor and ruler.

Please note that the specific measurements and angles used in this example are for illustrative purposes only. You can choose any angle measurements you prefer when drawing your own triangle.

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