Mystery Triangle Discussion by https://padlet.com/clbarne6/my7fx2j76v11 Choose one pair of triangles that you discovered in the worksheet and write out what pair, type of transformation, and your explanation for why you decided that particular transformation was used to form the relationship between the triangles. Once you have finished, comment on one other pair’s response that chose a different transformation and tell them, in a polite way, whether you think their explanation is correct or not and why. en-us 2018-04-16 23:26:38 UTC 2018-04-30 22:54:31 UTC hello@padlet.com Pair A and G clbarne6 https://padlet.com/clbarne6/my7fx2j76v11/wish/256340487 A mirrors G over the line of reflection and when a vertex is on the line of reflection, it overlaps G, meaning there is a fixed point on the line.

We know this because every point in E has been shifted up by a length to make B. Also, the images never overlap ever. 

They stay the same distance away and same angle away no matter where you move it!]]> 2018-04-30 22:41:34 UTC https://padlet.com/clbarne6/my7fx2j76v11/wish/256718050 Group 2 https://padlet.com/clbarne6/my7fx2j76v11/wish/256718216 Pair A, G is a reflection. We know for sure because we found a whole line, the mirror line, where the image and the preimage overlap. 

Moving A away from the line makes G move away. Moving A up the line moves G up the line and so on. ]]> 2018-04-30 22:43:35 UTC https://padlet.com/clbarne6/my7fx2j76v11/wish/256718216 Group 3 https://padlet.com/clbarne6/my7fx2j76v11/wish/256719105 C is the preimage which is transformed by a rotation of 90 degrees to produce I. We can tell because we found a single fixed point. 

Also, if you move the preimage left, the image moves perpendicular to the preimage. ]]> 2018-04-30 22:52:19 UTC https://padlet.com/clbarne6/my7fx2j76v11/wish/256719105
