Linear Pair Property

Let us look at these angle couples in terms of straight lines: Alternative inner angles: alterate " means "alternating sides" of the transverse. The name clearly indicates the "position" of these corners. Measurements are the same if the line is straight. Changing inner corners are "inside" (between the parallels ), and they "change" the sides of the shear.

Note that these are not neighboring corners (side by side that share a knot). lf the line is straight, it's the same size. Can also be backwards: . Cutting two straight parallels through a transverse, the alternating inner corners are the same. Once two contours are intersected by a transverse and the alternating inner corners are coincident, the contours are aligned.

Alternative outer angles: The term "alternate" means "alternating sides" of the shear. This name clearly indicates the "position" of these corners. Measurements are the same if the line is straight. Alternative outside corners are "outside" (outside the paralell lines), and they "change" the sides of the shear. Note that these angle values, like the alternative inner angle values, are not side by side.

lf the line is straight, it is the same in size. Cutting two straight parallels through a transverse, the changing outer angle is the same. Once two perpendicular line segments are intersected and the alternating outer angle segments are coincident, the line segments are aligned. Appropriate angles: This name does not clearly describe the "position" of these corners.

Corners are on the same side of the transverse, one inner and one outer, but not the other. Correspondingly, the corners are on the same side of the transverse in "corresponding" position. Measurements are the same if the line is straight. When you copy one of the corresponding angels and move it along the transverse, it matches the other corresponding one.

E.g. move ? 1 over the transverse axis downwards and it will match ? . lf the line is straight, it's the same size. Can also stand backwards and/or on its head: . Corresponding angle is the same when two straight line intersections are intersected by a shear. Corresponding ly, when two line are intersected by a transverse and the corresponding angle is the same, the line is perpendicular.

Inner angle on the same side of the transversal: Name is a descriptive term for the "position" of the two angle points. In case the pipelines are running concurrently, the actions are complementary. Those corners are exactly as their name says. These are " inside " (between the parallels ) and they are on the same side of the shear.

In case the line is running side-by-side, the inner angle on the same side of the transverse axis is complementary. Cutting two straight parallels through a transverse, the inner corners on the same side of the transverse are complementary. Once two contours are intersected by a transverse and the inner corners on the same side of the transverse are additional, the contours are straight.

Besides the 4 pair of designated angels used when working with multiple line parallelism (see above), there are also some pair of "old friends" who also work with multiple line parallelism. Upright angles: Plane curves appear when a line intersects a line. ALWAYS, perpendicular angels are the same regardless of whether the line is perpendicular or not.

We have 4 sentences of perpendicular brackets in this chart! Keep in mind: The line does not have to be perpendicular in order to have perpendicular corners of the same size. Upright corners are matched. Pair linear angles: One pair of line segments are two neighboring corners that form a single line. Corners that form a linear pair are ALWAYS complementary. As an even corner contains 180º, the two corners that form a linear pair also contain 180º when their dimensions are added (which makes them additional).

In the case where two squares make a linear pair, they are complementary.
