Yes, it is true that angle 60 degrees has two edges in the angle parts.
They are two edges that make a 90 degree angle. However, the term is also loosely used for edges that make a 90 degree angle with the horizontal.
The angle is 90 degree
In geometry and trigonometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex or vertex of the angle (vertices in plural).With solid figures, like pyramids or polyhedrons, a vertex is a corner where three or more of the faces meet.Remember,* faces are the flat sides.* Edges are the lines where two of the faces meet.* Vertices are the corners where three or more of the faces meet.
a right angle is exactly a 90 degree angle. for example, there are 4 right angles on a square, the corners are right angles. like the edges on papers that is a right angle. an oblique line is smaller than a right angle.
This would be just a single node, since no edges (you can think of degree as the number of edges connected to a node). If you are talking about the in-degree, or out-degree of a node being zero, this can happen many times in a directed graph (in-degree = # edges going IN to node, out-degree = # edges going out...).

An endpoint where two edges intersect on a polyhedron is called a vertex.

if one corner i think its called L-shape or 90 degree angle.

the answer is accute
Parallel edges are equidistance apart whereas perpendicular edges meet at right angle as in a square or a rectangle.
There are 7 edges.
A right angle is a 90 degree angle.It can also be known as a square angle. The two edges of the angle are perpendicular to each other (which is a 90 degree angle), as they are in a square.A right angle is a 1/4 turn. (A full circle turn is 360 degrees; a quarter turn is 90 degrees.)If you take your index finger and hold it straight up and your thumb on the same hand out creating an L shape, that is a good example of a right angle.A right angle is a angle that has 90 degreesA right angle is a corner that measures exactly 90 degreesIt's an angle that bisects the angle formed by two halves of a straight line. It is measured at 90°.
