# Complete polygons with missing coordinates

I can mark points specified as a translation from the origin.

## Lesson details

### Key learning points

- Use knowledge of polygon properties to identify a missing vertex.
- Use known coordinates to plot a missing coordinate.

### Common misconception

Pupils may not correctly identify the type of polygon (e.g., rectangle, square, parallelogram), leading to errors in determining the missing coordinate.

Encourage pupils to first identify the polygon by examining the given vertices. Review the properties of common polygons (e.g., opposite sides of a rectangle are equal and parallel). Use visual aids or models to reinforce these properties.

### Keywords

Vertex / vertices - A vertex is the point where two or more line segments meet. The plural is vertices.
