8th Unit 2 Test Written Response

This assignment will help you understand the concepts of congruent and similar figures, as well as how transformations affect these figures. You will explore the vocabulary related to these concepts and explain the effects of different types of transformations on side lengths and angles.

Han’s teacher asked him to draw a polygon similar to polygon . Here is his work. Did Han correctly draw a similar polygon? Explain your reasoning. Be sure to discuss what has happened to the angle measurements and the side lengths and how that can help you determine if it is a scaled copy.

Describe how the side lengths and angles are affected by rigid transformations(rotations, reflections and translations) and how they are affected by dilations.

Explain which kind of transformations create congruent shapes and what kind of transformations create similar shapes.

Explain how the shape will be different if it is dilated by a scale factor of 3 vs a scale factor of ½.

Line A has a slope of ¼. What slope does line B need to have to be parallel to line B?

Line A has a slope of ¾. What slope does line B need to have to be perpendicular to line A?
