A path can contain two kinds of anchor points: smooth points and corner points.
All smooth points, and some corner points, have tangent lines passing through them. Canvas displays the tangent lines when a point is selected.
A corner point can have one, two, or no tangent lines.When you select a corner anchor point with two tangent lines, each tangent line can move independently.

When you create paths with only straight segments, the anchor points are corner points. When you draw curved paths with the Curve, Freehand, or Auto Curve tools, the anchor points are smooth points. Adding anchor points to curved segments produces smooth points.
You can edit, reshape, and resize two adjoining curve segments independently by converting their smooth anchor point to a corner point.
Tab-click a corner point’s handle to snap the other tangent line into alignment and smooth the path
To smooth out a sharp turn in curved segments, change the corner point between them to a smooth point.
The corner point must have two tangent lines for this procedure. If it has fewer than two, first add tangent lines to the point.
An anchor point can have as many as two tangent line segments. Corner points can have one, two, or no tangent lines, and smooth points must have two. You can quickly convert a smooth point to a corner point by deleting one of its tangent lines. Also, to convert a corner point with one or no tangent lines to a smooth point, you must add tangent lines.
Straighten a curved segment by selecting it and using the Straighten command in the context menu. This command deletes the tangent line(s) that curve the segment.
To adjust the shape of a curve, in addition to moving points and segments along the path itself, you can adjust the tangent lines that control the curve. The angle of the tangent line affects the curve shape, while the length of the tangent line affects the size of the segment.
At a smooth anchor point, adjusting the angle of a tangent line affects the curves on both sides of the anchor point. At a corner anchor point, you can reshape the segments on each side independently. (See -Reshaping Paths by Editing Anchor Points.)
To do this

Delete an anchor point
Ctrl+Shift-click anchor point
Change the length of the tangent lines on both sides of a smooth anchor point at the same time
Ctrl-drag tangent line handle

Shift-drag tangent line handle
Move tangent line segment independently (change anchor point from smooth to cusp)
Tab-drag tangent line handle
Align tangent line segments (change corner point with two tangent lines to smooth point)
Tab-drag tangent line handle
Add tangent line to an anchor point
Tab-drag an anchor point
Delete an anchor point’s tangent lines
Tab-click the anchor point or endpoint
Close an open path
Alt-click an endpoint
Reshape a segment without changing the tangent line angles
Press Tab and drag the segment
Reshape A segment and adjacent segments
Press Alt and drag a segment
Some vector objects have specialized properties and unique edit modes instead of the standard Path Edit mode; e.g., you cannot directly edit the path segments of dynamic objects, concentric circles, grids, multigons, spirals, and objects modified by the Envelope or Extrude commands; however, you can convert these objects to paths so you can edit them the same as any other vector object.
If you create paths from a specialized vector object, the new shape does not have the same unique editing capabilities as the original; e.g., if you convert a Multigon star object to paths, you can no longer use the edit handles that let you adjust the depth and twirl of the points. Similarly, placed dynamic objects are no longer linked to their parent objects in the Symbol Library palette after you convert them to paths.
You can also convert text so you can reshape characters as vector objects. This has the benefit of making the characters independent of their fonts; the font is no longer required to view and print the characters properly. However, once you convert text to paths, you can no longer perform text operations, such as editing, spell-checking, and formatting, on the text. Also, characters with “holes” in them (such as a, b, d, e, g, o, p, r, and q) are converted to composite paths, which cannot be extruded.
This operation facilitates the rapid conversion of vector objects into a simple path. Now any Canvas object or a group of objects can be converted into simple paths. At the same time, these objects will maintain their Canvas inks settings and stroke types.
The Convert to Simple Paths command breaks down everything Convert to path does not. It also breaks down strokes and inks to simple, yet editable, Bézier paths and polygons.
At this point, all high level drawing features that are contained in the object are reduced to individually editable polygon and Bézier objects.
You can convert Bézier curves, ovals, text objects, grouped objects, composites, and EasyShapes to polygons.
An illustrator may find it necessary to outline a path stroke when working with logos, intricate artwork, or traced images, etc., especially if the illustrations will be resized.

Even when reduced, the object maintains stroke size
Illustration with a converted stroke resized by 50%
After conversion, the stroke size is no longer a factor when reducing objects
You can apply this command to more than one selected vector object or even a grouped object.

When you convert multiple objects, characters, or specialized vector objects to paths, Canvas creates a separate path for each shape and groups them.
Choose Object | Ungroup to separate them.
For example, if you convert a five-letter word to paths, the resulting object is a group of five paths. To edit just one of the five paths, first choose Object | Ungroup. Or, use the Direct Selection tool to select one path without ungrouping.
Create openings in a filled path by incorporating multiple paths into a single, composite path. Areas between the paths and areas where the paths intersect are transparent.
When using the Symmetrical Drag feature, you can easily create a symmetrical design from a circle, rectangle, or a complex group of objects.
You also have the ability to select all of the control points, and drag. Doing so will allow you to quickly resize the object while retaining proper object constraints.
When you drag the selected control points, notice that the shape is resized from the center of the object.
Dragging will resize the object
