Question

За допомогою транспортера накресліть <DBC=140° та провести його бісектрису​

Answer 1

Ответ:

140÷2= 70° (це градус обох кутів після проведення бісектриси)

Объяснение:

Бісектриса—це промінь який поділяє кут на дві рівні частини, і який починається з вершини кута

Answer 2

Drawing an Angle of 140° and Its Bisector Using a Compass

To draw an angle of 140° and its bisector using a compass, follow these steps:

1. Draw the Initial Angle (140°): - Start by drawing a straight line using a ruler. - Mark a point on the line to represent the vertex of the angle. - Place the compass on the vertex and draw an arc to create the initial angle of 140°.

2. Bisecting the Angle: - With the same compass width, place the compass on one of the arms of the angle and draw an arc that intersects the two arms of the angle. - Without changing the compass width, place the compass on the other arm of the angle and draw another arc that intersects the previous arc. - Draw a straight line from the vertex of the angle to the point where the two arcs intersect. This line bisects the angle, dividing it into two equal angles.

This method allows you to accurately draw an angle of 140° and its bisector using a compass.
