Question

I forgot how to prove congruence and I need help.

Answer 1

Given the triangle ABC

A(2, 3)

B(4, 2)

C(3, 5)

Given the following transformation rules:

The first,

$(x,y)\rightarrow(x-4,y-1)$

The transformation rule represents shifting 4 units left and 1 unit down

The shift transformation will give a congruence triangle

So, the answer will be: Congruent to the original

=========================================================

The second rule,

$(x,y)\rightarrow(1.5x,1.5y)$

The transformation rule represents a dilation with a factor of 1.5

So, the sides of the new triangle will be larger 1.5 times than the original

So, the sides of the triangles will be proportions with a factor of 1.5

So, this will give a similar triangle

The answer will be: Similar to the original.
