The sum of the angles around a vertex point in a plane will always be 360o. Picture a bicycle wheel with all its spokes radiating out from the hub. Now pick two spokes to form a vertex. Find the angle of your vertex, and then subtract it from 360o. As there are 360o in a circle, and your figure (the vertex) is a slice of the circle, its angle plus all the rest of the arc about the vertex will sum to 360o. If you've discovered the angle of your vertex, you cannot help but find the sum of the rest of the angles (if there are more than one) around your vertex.
They are adjacent angles.
not all congruent angles are vertical angles. Vertical angles must share a vertex.
have the same vertex. be congruent.
The exterior and interior angles of each vertex of a polygon add up to 180 degrees.
If your "53" is in degrees, then the vertex angle is 74 degrees.
In a tessellation, the angle sum around a vertex depends on the type of polygons used in the tessellation. For regular polygons, the angle sum around a vertex is always 360 degrees. This is because each interior angle of a regular polygon is the same, so when multiple regular polygons meet at a vertex in a tessellation, the angles add up to 360 degrees.
It is 360 degrees.
They add to 360 degrees.
Yes. Regular or irregular, the angles at vertices must sum to 360 deg otherwise you will have gaps in the tessellation.
The angles at any point is space add to 360 degrees. So, at any vertex in a tessellation, the angles of the vertices meeting there must sum to 360 degrees.
I don't know what a tessellation vertex is but I will try to Answer it I think it means the endpoint of a vertex which is also called vertices,which is the pointy ends of the vertex.
The total angles around a point is 360 degrees. Since there can be no gaps or angles, all of the angles meeting at any vertex must sum to 360 degrees.
360 degrees, but this assumes that there are any angles. There need not be any angles - as illustrated by MC Escher in his set of Symmetry artwork.
On a protractor and at each corner (vertex) of the polygon.
Gee, Hard problem
It would be (90) - (1/2 of the vertex angle)
Some facts on tessellations are that there are different types of tessellations such as regular and semi-regular. In tessellations, each vertex will have a sum of 360º which is what all of the angles should come out to.
