Question 1

Which sequence of similar transformations could map △ABC onto △A'B'C'?dilation and reflectiondilation and translationtranslation and rotationtranslation and reflection

Revolt · Accepted Answer

dilation and reflection

Question 2

rotation of 90 degrees about Breflection across ABdilation with center Ctranslation left

Revolt · Accepted Answer

translation left; The first transformation mapping △ABC to △A'B'C' is a .: translation left; The second transformation mapping △A'B'C' to △A''B''C' is a .: dilation with center C'

Revolt · Accepted Answer

YXV; We are given that XY is parallel to ZW. If XZ is a transversal that intercepts XY and ZW, angle and angle are alternate interior angles. Since XY is parallel to ZW, we know that these angles are . We: YXV; We are given that XY is parallel to ZW. If XZ is a transversal that intercepts XY and ZW, angle and angle are alternate interior angles. Since XY is parallel to ZW, we know that these angles are . We: WZV; We are given that XY is parallel to ZW. If XZ is a transversal that intercepts XY and ZW, angle and angle are alternate interior angles. Since XY is parallel to ZW, we know that these angles are . We: congruent; We are given that XY is parallel to ZW. If XZ is a transversal that intercepts XY and ZW, angle and angle are alternate interior angles. Since XY is parallel to ZW, we know that these angles are . We: vertical; We are given that XY is parallel to ZW. If XZ is a transversal that intercepts XY and ZW, angle and angle are alternate interior angles.
