The angle of reflection is the angle the to the reflecting surface.
1. incident ray makes with a parallel line
2. incident ray makes with a perpendicular line
3. reflected ray makes with a perpendicular line
4. reflected ray makes with a parallel line

3. reflected ray makes with a perpendicular line

Explanation:

- The angle of incidence is defined as the angle between the incident ray and the perpendicular to the surface

- The angle of reflection is defined as the angle between the reflected ray and the perpendicular to the surface

According to this second definition, we see that the correct answer that completes the sentence is (3):

The angle of reflection is the angle the 3. reflected ray makes with a perpendicular line to the reflecting surface.

The law of reflection also states that the angle of reflection is equal to the angle of incidence.

porque la cantidad de gases de efecto invernadero alcanzó un nuevo máximo sin precedentes, causando daños muy graves a esta, por eso es importante monitorearla, para controlar el porcentaje de daños que esta causa y poder reducirlo o mantenerlo.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
