Without any equality signs none of the given terms can be classed as equations
It is the sum of the y-coordinates of the vertices divided by the number of vertices.
A parallelogram has 4 vertices
A parallelogram has four vertices- it's a quadrilateral.
Yes and it has 4 of them.
That depends on where the triangle ABC is located on the Cartesian plane for the coordinates of its vertices to be determined.
It is the sum of the y-coordinates of the vertices divided by the number of vertices.
A parallelogram has 4 vertices
All parallelograms have 4 vertices.
A parallelogram has four vertices- it's a quadrilateral.
4 sides and 4 vertices
Four.
4.
Yes and it has 4 of them.
That depends on where the triangle ABC is located on the Cartesian plane for the coordinates of its vertices to be determined.
how does translation a figure vertically affect the coordinates of its vertices
No- the vertices of a rectangle are the four coordinates (corners) not the midpoints.
It depends on what the coordinates of the first three vertices are!
