# Translations Discovery Activity

Use the tools to: 1) Create a polygon in the coordinate plane. Do this by clicking on the polygon tool (triangle with 3 blue vertices). Click on the graph to make the first vertex, click any where else on the graph to make other vertices, then click back on the first vertex ﻿to close/complete the shape. It does not matter what the shape is. Click on all the vertices (use ctrl to ﻿select more than one at a time) then click on the lock to lock the shape in place. 2) Label the vertices. Right click on the point(s), go to settings, make sure "show label" is checked and ﻿change it to show name AND label. You should now be able to see the letter and coordinate of each of ﻿your ﻿vertices. 3) Use the vector tool to create a vector﻿﻿ with the endpoint at the origin. You can choose to make the vector ﻿point in any direction you choose with any magnitude (length). Label the vector with the name and ﻿label. You should be able to see what looks like an order pair for the vector. This tells you the direction ﻿and magnitude of that particular vector.
