Q: A: ### Quick Answer

A right angle has 90 degrees. Angles are measured on a scale from 0 to 360 degrees. Right angles represent one-fourth of a full 360-degree revolution.

Know MoreRight angles have their own symbol, which is a square in the corner where the two lines of the angle meet. Math has six kinds of angles: acute, right, obtuse, straight, reflex and full. Acute and obtuse angles are defined in relation to right angles, as acute angles are less than 90 degrees and obtuse angles are between 90 and 180 degrees. A straight angle is exactly 180 degrees, and a full angle is exactly 360 degrees. Reflex angles fall between 180 and 360 degrees.

## 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 the intersection of two rays with a common endpoint?

A:

Full Answer >**The vertex is the common endpoint when two rays intersect to form an angle. The formed angle is named by using three points.**One point is on each of the two rays, and the third is at the vertex point.Filed Under: - Q:
## 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 an orthogonal vector?

A:

Full Answer >**An orthogonal vector is a vector that is at an angle of 90 degrees, or perpendicular, to another vector.**Up to three vectors can be mutually orthogonal to each other in a three-dimensional space.Filed Under:
