a scale factor of to form triangle DEC. Which
statements about the two triangles must be
true? Select three options.
DAABC-ADEC

2mzA=3m2D

Answer 1

Triangle ABC is similar to triangle DEC, ∠B ≅ ∠E and 3DE = 2BC

What is transformation?

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a scale factor.

Right triangle ABC is reflected over AC, then dilated by a scale factor of 2/3 to form triangle DEC, hence:

Triangle ABC is similar to triangle DEC, corresponding angles are congruent (∠B ≅ ∠E) and DE = (2/3)BC i.e. 3DE = 2BC
