Sliding a Shape

Part of the Transformations & Constructions section of Coddy's Geometry journey. Lesson 1 of 60.

$Triangle PQR and its image, slid 3 right and 2 up$

Triangle PQR slides 3 right and 2 up. Its new position is its image, P'Q'R'. Read P' as "P prime". Every point moves the same distance in the same direction. This move is a translation. We write it $\langle a,\ b \rangle$ : a steps right and b steps up. This one is $\langle 3,\ 2 \rangle$ .

Challenge

Triangle ABC and a dashed target are on the grid. Find the translation that moves ABC exactly onto the target. Then apply it.

Then press Check.
