Q:A:### Quick Answer

**A symmetrical pattern is a pattern in which converging lines form an angle that somewhat resembles an acute angle.** When two patterns are symmetrical, one becomes exactly like another when flipped or turned, according to Primary Resources.

A common example of symmetry is a reflection. The image of an object looks exactly like the object when turned through an angle of 180 degrees. In geometry, some shapes have lines of symmetry. Such a shape is symmetrical because, when folded along that line of symmetry, it gives two equal halves that look exactly the same. Symmetrical patterns are evident among regular objects, or objects with proportional form.

## What is the common end point of the sides of an angle?

A:

Full Answer >**The common endpoint of the sides of an angle is called a vertex.**For example, triangles have three vertices, while squares have four. These common endpoints are often colloquially called corner points, though this may result in confusing them with angles.Filed Under: - Q:
## How do you read a protractor?

A:A protractor is an inexpensive math tool used to measure the sharpness of an angle in a geometric shape. Reading a protractor is fairly simple.

## What is angular uncomformity?

A:

Full Answer >**An angular unconformity is a geological phenomenon where an older layer of rock sits directly beneath a much younger layer of rock because the older layer was forced up at an angle, eroded, and younger rock deposited on top of it.**An angular unconformity only stays constant for a relatively short distance into a rock face. Digging horizontally into the older rock reveals younger angled layers.Filed Under: - Q:
## What is a vertex angle?

A:

Full Answer >**A vertex angle refers to the angle that is formed by the two lines crossing at a vertex.**When asked for a vertex angle, the intended query is typically for the size of the angle in degrees or radians.Filed Under:
