About Coordinate Translations
A coordinate translation moves every point by the same horizontal and vertical shift. The shape does not turn. It does not resize. It only slides across the plane. This calculator helps you track that slide with exact arithmetic, signed values, and clear coordinate notation.
Why Translations Matter
Translations are used in analytic geometry, vectors, mapping, motion diagrams, and computer graphics. A designer may move a logo without changing its shape. A student may shift a triangle on graph paper. A physics problem may describe displacement from one position to another. Each case uses the same idea. Add the shift to the starting coordinate, or subtract it when you need the original point.
What This Tool Handles
The calculator supports forward translation, reverse translation, and vector discovery. Forward mode finds the image point after a translation. Reverse mode finds the preimage point before the movement. Vector mode finds the translation rule from an original point and an image point. You can work in two dimensions or include a z coordinate for space geometry.
Reading the Results
The output gives the ordered pair or ordered triple. It also shows the translation rule, magnitude, direction angle for plane work, and distance checks. These extra values help confirm the answer. They are also useful when a teacher asks for supporting work, not just the final coordinate.
Accuracy Tips
Always keep signs attached to each value. A shift of negative four means move left, not right. A positive y shift means move upward on a standard graph. Use decimals only when your problem needs them. Fractions can be entered as decimal equivalents. Check the plotted movement after calculating, especially when several points form a shape.
Practical Use
For polygons, calculate each vertex with the same vector. Then connect the new points in the original order. Matching side lengths confirm that the translation was done correctly. The example table below shows common cases. Use it to test the calculator before entering your own coordinate problem.
Study Benefit
Writing the rule beside the coordinate prevents sign mistakes. It also builds a clean habit for later transformations, including reflections, rotations, dilations, and combined mappings in algebra, geometry, and physics. Use results for lessons and review.
