Answer 2

a) Переместите фигуру A вокруг точки O на 90° и отметьте фигуру как B.

To rotate figure A around point O by 90°, you can follow these steps: 1. Draw a circle with point O as the center and a radius equal to the distance between point O and any point on figure A. 2. Draw a line segment connecting point O and any point on figure A. 3. Measure the length of the line segment and mark a point on the circle that is the same distance away from point O. 4. Connect the marked point on the circle with point O to form a line segment. 5. The line segment connecting point O and the marked point on the circle represents the new position of figure A after rotating it by 90° around point O. 6. Label this new position of figure A as B.

b) Нарисуйте фигуру, симметричную относительно оси O, и отметьте получившуюся фигуру как C.

To draw a figure symmetric to figure A with respect to the axis O, you can follow these steps: 1. Draw the original figure A. 2. Draw a line passing through point O, which will act as the axis of symmetry. 3. For each point on figure A, draw a line segment that is perpendicular to the axis of symmetry and intersects the axis at a point equidistant from the original point and the axis. 4. Connect the corresponding points on the line segments to form the symmetric figure. 5. Label this symmetric figure as C.

c) Скопируйте фигуру A параллельно вектору a и отметьте получившуюся фигуру как D.

To copy figure A parallel to vector a, you can follow these steps: 1. Draw the original figure A. 2. Draw a line segment representing vector a, starting from any point on figure A. 3. Measure the length of vector a and mark a point on the line segment that is the same distance away from the starting point. 4. Draw a line segment connecting the corresponding points on figure A and the marked point on the line segment representing vector a. 5. This line segment represents the copied figure of A parallel to vector a. 6. Label this copied figure as D.

Please note that without specific information about the shape or characteristics of figure A, it is not possible to provide more detailed instructions.
