Which sequence of transformations creates a similar, but not congruent, triangle? (4 points) 1) Rotation and translation 2) Reflection and rotation 3) Dilation and rotation 4) Translation and reflection

  3) Dilation and rotation

Step-by-step explanation:

Rotation, translation, and reflection are rigid motions. They always result in congruent figures. If you don't want a congruent figure, you need to have dilation by a factor other than 1.

Similar, but not congruent, figures will be created by ...

  Dilation and Rotation

step-by-step explanation:

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
