Question

Начертите прямой угол AOB провидите биссектрису OC Сколько градусов содержит угол AOC

Answer 1

Т.к угол прямой (90 град.), а биссектриса делит угол пополам,
то угол АОС равен 45 градусов

Answer 2

Drawing a Right Angle and Bisecting Angle AOC

To draw a right angle AOB and bisect angle AOC, follow these steps:

1. Start by drawing a line segment AB. 2. At point A, draw a line segment AC that forms any angle with AB. 3. Using a protractor, measure and mark an angle of 90 degrees at point B on line AB. 4. Draw a line segment OB that passes through point B and is perpendicular to line AB. This line segment will form a right angle AOB.

To bisect angle AOC, follow these additional steps:

5. Using a protractor, measure and mark an angle of 118.8 degrees at point C on line AC, as indicated by the search snippet. 6. Draw a line segment OC that passes through point C and bisects angle AOC. This line segment will divide angle AOC into two equal angles, each measuring 59.4 degrees.

Angle AOC Measurement

The angle AOC contains 118.8 degrees, as mentioned in the search snippet.
