Question

How do you do congruence and transformations

Answer 1

I love this unit a-lot (super fun)

So Congruent/Congruence is, For example If you have two triangles on a coordinates grid with the same coordinates than that would mean they're congruent. Shortened down would be 

Same shape same coordinates same dimension same size (same everything)

Transformations would be Rotating a shape clockwise(CW)...right) or counterclockwise(CC Left) 

Or Dilation which is making the shape smaller or bigger based on a scale factor.
  
Or reflection

How you would perform Reflection is reflect the shape over either the X-axis 
Or the Y-axis 

How you would perform a Translation would be to literally move the shape right left up or down.

How you would perform a Dilation(scaling) would be to pick a scale factor and either decrease or increase the size of the shape according to the scale factor number 

How you would perform a Rotation would be to pick a point of rotation (P.O.R) and then pick your measure º such as 90º clockwise and rotate accordingly. 


Hope it helps :)
