Question

Диагонали квадрата АВСД пересекаюися О .Найдите угол между вектороми АВ и АС

Answer 1

В квадрате все диагонали пересекаются под углом 90 градусов, поэтому АВ =90 град, АС= АВ+ВС= 90+90 = 180 ГРАД

Answer 2

Finding the Angle Between Vectors AB and AC in Square ABCD

To find the angle between vectors AB and AC in square ABCD, we can use the fact that the diagonals of a square bisect each other at 90 degrees. This means that the angle between the diagonals is 90 degrees, and we can use this information to find the angle between vectors AB and AC.

Given that the diagonals of square ABCD intersect at point O, we can use the properties of squares to determine the angle between the vectors.

Step 1: Find the Angle Between the Diagonals - The diagonals of a square intersect at 90 degrees. - Therefore, the angle between the diagonals of square ABCD is 90 degrees.

Step 2: Use the Angle Between Diagonals to Find the Angle Between Vectors - Since the diagonals of the square intersect at 90 degrees, we can use this information to find the angle between vectors AB and AC.

Step 3: Calculate the Angle - The angle between vectors AB and AC can be calculated using the information about the diagonals of the square and the properties of vectors.

Based on the given information, the angle between vectors AB and AC can be determined using the fact that the diagonals of a square intersect at 90 degrees.
