# CTE Resource Center - Verso - Geospatial Technology II Task 1025825691

# Modify vector shapefiles spatially to create, modify, and delete point, line, and polygon features.

## Definition

Modification should result in a more relevant shapefile.

## Process/Skill Questions

• What would occur if more vertices were used to create the polyline?
• When is it feasible to delete a feature as opposed to modifying it?

## Mathematics

### G.3

The student will solve problems involving symmetry and transformation. This will include
1. investigating and using formulas for determining distance, midpoint, and slope;
2. applying slope to verify and determine whether lines are parallel or perpendicular;
3. investigating symmetry and determining whether a figure is symmetric with respect to a line or a point; and
4. determining whether a figure has been translated, reflected, rotated, or dilated, using coordinate methods.

### G.9

The student will verify and use properties of quadrilaterals to solve problems, including practical problems.
