Recall

Retrieve the key fact or method needed for vectors and translations.

Core practice

A triangle has vertices (0,0),(2,1),(1,4). Translate by (−3,2). State all new vertices.

Reasoning

A translation maps A=(−2,5) to A'=(4,−1). Show where B=(3,3) maps.

What Went Well (WWW)

I selected the correct geometric fact, theorem, formula or transformation and used a clear diagram with appropriate labels and units.

Even Better If (EBI)

I will name the fact or theorem, show the substitution or construction step and check whether the size, direction and units of the result are reasonable.

Stretch and deep challenge

Stretch: A triangle has vertices (0,0),(2,1),(1,4). Translate by (−3,2). State all new vertices.

Deep challenge: A translation maps A=(−2,5) to A'=(4,−1). Show where B=(3,3) maps.
