1 a restraining, arresting, or checking of the action of an organ or cell. 2  the reduction of a reflex or other activity as the result of an antagonistic stimulation.  a state created at synapses making them less excitable by other sources of stimulation.
Angles 2 and 7, as well as angles 3 and 6 are examples of alternate interior angles. Similarly, we also have alternate exterior angles that are located outside of the two intersected lines and on opposite sides of the transversal. An example of this relationship would be angles 1 and 8, as well as angles 4 and 5. The last angle relationship is consecutive interior angles. These angles are located on the same side of the transversal and inside of the two lines.
So that's one way to think about it, but this is just general terminology for different types of angles. Less than 90 degrees, you have an acute angle. At 90 degrees, you have a right angle. Larger than 90 degrees, you have an obtuse angle.
