Question

7
triangle mno is dilated to create triangle mno.
which one of the following statements is
not true about the angles of the two triangles?
a the measure of angle m is congruent to the measure of angle m.
b the measure of angle o is congruent to the measure of angle o.
c each pair of corresponding angles of triangles mno and mno are not congruent because triangle mno was dilated by a scale factor of $\frac{1}{2}$ to create triangle mno.
d each pair of corresponding angles of triangles mno and mno are congruent even though triangle mno was dilated by a scale factor of $\frac{1}{2}$ to create triangle mno.

Explanation:

Dilation is a transformation that changes the size of a figure but preserves its shape, meaning all corresponding angles of the original and dilated figures are congruent regardless of the scale factor. Options A, B, and D correctly state that corresponding angles are congruent. Option C incorrectly claims corresponding angles are not congruent due to dilation, which contradicts the properties of dilation.

Answer:

C. Each pair of corresponding angles of triangles MNO and M'N'O' are not congruent because triangle MNO was dilated by a scale factor of 1/2 to create triangle M'N'O'.
