A dihedral angle is the angle between two intersecting planes.
The word "intersect" has 2 meanings. It can mean divide something by passing or lying across it. It can also mean two or more things passing or lying across each other.
Depends on which intersect you are talking about. I am going to assume you mean where a line intersects the axis in a two dimensional plane. An intersect is the point on the x or y axis where a line crosses it.
It means that two lines intersect each other at a ninety degree angle.
No. If two lines intersect they cross each other. To bisect each other, means that the lines not only intersect but that also that the point where the two line[ segment]s cross is the mid point of both of the line[ segment]s. Examples, consider: The diagonals of a kite ABCD with sides AB & AD equal (2 cm each), and BC & DC equal and twice the length of the other two sides (4 cm each). The diagonals AC and BD intersect each other; BD is bisected by AC but AC is NOT bisected by BD. The diagonals of a right angle trapezium ABCD with ∠DAB and ∠ADC right angles (so sides AB and DC are parallel) and with sides AB = 2 cm, CD = 14 cm and AD = 5 cm (side BC = 13 cm). The diagonals AC and BD intersect, but NEITHER bisects the other. The diagonals AC and BD of a square ABCD not only intersect each other, but they also do, in this case, bisect each other.
A dihedral angle is the angle between two intersecting planes.
their slopes are negative reciprocals of each other. and they make a right angle when they intersect.
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 two lines intersect each other at right angles, that means that the measure of each angle between the two lines is 90o. Another way of stating this is to say that two lines are perpendicular.

It means the point at where the x and y axes intersect each other at 90 degrees on the Cartesian plane
Yes. But it does not mean it is fully. It partly is not. It is if both lines are in the same plane. But if they are in different planes, then they won't intersect.
On the Cartesian plane (0, 0) is the point of origin where the x and y axes intersect each other at 90 degrees.
When 2 lines intersect, 4 angles are formed. The angles that are directly opposite to each other are called opposite angles.
