Because they represent a pair of coordinates
On a Cartesian plane (or one using polar coordinates), the vertex of the angle must be at the origin and one of the rays must lie along the positive x-axis (point towards the East).
the origin of few and far between is that a little goes along way
Draw a line from any vertex to a point on one of the adjacent sides and cut along it.
two slightly smaller triangles of equal size :)
The medians of a triangle are concurrent and the point of concurrence, the centroid, is one-third of the distance from the opposite side to the vertex along the median
The vertex of a prism is a corner along the side of the prism. There are 8 vertices on a rectangular prism.
On a Cartesian plane (or one using polar coordinates), the vertex of the angle must be at the origin and one of the rays must lie along the positive x-axis (point towards the East).
It depends on what the motion is. If the square is sliding along a straight line then the path of the vertex is a straight line. If the square is rotating, the answer will vary according to the location of the centre of rotation.
The x-component of the electric field at the origin O is closest to zero because the electric field due to Q1 is along the -x direction and the electric field due to Q2 is along the +x direction. These two fields cancel each other out at the origin, resulting in a net field of zero along the x-axis.
Suppose you have a triangle whose vertices are A, B and C, and the sides opposite these vertices are a, b and c, respectively. Cut out the triangle. Fold it so that vertex B meets vertex C. Mark the point where this fold is on side a. Mark this point as D and fold along AD. Fold it so that vertex A meets vertex C. Mark the point where this fold is on side b. Mark this point as E and fold along BE. Fold it so that vertex A meets vertex B. Mark the point where this fold is on side c. Mark this point as F and fold along CF. The three folds, AD, BE and CF meet at the circumcentre. You do not need all three - any two of them will do.
to slide or move a figure to a new position along a striaght line
the origin of few and far between is that a little goes along way
Origin because it is the highway that runs along the cost
Cone ( not including the vertex ) Cylinder ( APEX )
A 30-60-90 right triangle
Draw a line from any vertex to a point on one of the adjacent sides and cut along it.
No. A full angle is a segment of a line which goes to a vertex and returns along the same path. Any point on the line segment, other than the vertex, will trace out a circle but the angle itself is NOT a circle.
