...parallel to each other.
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
No but its diagonals are perpendicular to each other
Not always because the diagonals of a rectangle bisect each other but they are not perpendicular to each other.
Yes the 4 corners of a rectangle are perpendicular to each other and its opposite sides are parallel to each other.
no planes are not perpendicular to each other because for air resistance the planes are designed in a such way that air is avoided to back side and they are inclined to each other.
...parallel to each other.
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
There are 6 equivalent (111) planes in an orthorhombic crystal system. This is because in an orthorhombic crystal system, the axes are of different lengths and perpendicular to each other, creating 6 symmetrical orientations for the (111) planes.
Perpendicular refers to two lines, planes, or surfaces that intersect at a right angle (90 degrees). In geometry, perpendicularity indicates a relationship where the lines or surfaces are oriented at right angles to each other.
The diagonals of a rhombus are perpendicular to each other and are bisected at 90 degrees
No but its diagonals are perpendicular to each other
In a square adjacent sides are perpendicular to each other and opposite sides are parallel to each other.
Perpendicular refers to two lines or surfaces that intersect at a 90-degree angle, forming a right angle. It is a geometrical term used to describe a relationship between two objects that are perpendicular to each other.
If the diagonals are congruent and are perpendicular bisectors of each other then the parallelogram is a square. If the diagonals are not congruent but are perpendicular bisectors of each other then the figure would be a rhombus.
Perpendicular lines can not be parallel to each other but they can be to other lines.
Yes, the sum of two perpendicular vectors has the same length as the original vectors, and they are also perpendicular to each other. However, the difference of two perpendicular vectors may not have the same length as the original vectors, but they will still be perpendicular to each other.
