This mini lesson introduces to students to formal translations of a shape. Emphasis on developing the 'vector' as the way to descibe a translation. Students have an opportunity to play with translations in a guided fashion using Geogebra applets.

In the above box, click the translate tool button (looks like 2 arrows) and then click the blue triangle and the vector u1. Describe what happened to the triangle.

Move the vector u1 such that the head (arrow) end of the vector is exactly on a lattice point (a corner). What is the SLOPE of the vector? Enter your answer as a fraction of the form a/b.

Using the slope as your guide, describe what happened to the triangle. Use words like "up/down" and "left/right".

A vector is a way of describing to someone HOW to move an object using the x & y axes as reference. A vector is written in the form < 3, -7 > which means "go right 3 and then down 7" since the x part is positive 3 and the y part is -7.
Write the vector u1 from above in the proper vector form. Give your answer in the form <a,b> using no spaces!
