- Understand Congruence And Similarity Using Physical Models, Trans- Parencies, Or Geometry Software.
- State Standard:
- Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
- Topic A begins by demonstrating the need for a precise definition of dilation instead of “same shape, different size” because dilation will be applied to geometric shapes that are not polygons. ...
- Student Outcomes Students know an informal proof of why dilations are degree-preserving transformations. Students know an informal proof of why dilations map segments to segments, lines to lines, and...
- Student Outcomes Students describe the effect of dilations on two-dimensional figures using coordinates.
- Student Outcomes Students verify the converse of the Fundamental Theorem of Similarity experimentally. Students apply the Fundamental Theorem of Similarity to find the location of dilated points on...
- Student Outcomes Students experimentally verify the properties related to the Fundamental Theorem of Similarity (FTS).
- Student Outcomes Students know that dilations map circles to circles and ellipses to ellipses with the same shape. Students know that to shrink or magnify a dilated figure back to its original size...
- Student Outcomes § Students learn how to use a compass and a ruler to perform dilations. § Students learn that dilations map lines to lines, segments to segments, and rays to rays. Students know...
- Student Outcomes Students learn the definition of dilation and why “same shape” is not good enough to say two figures are similar. Students know that dilations magnify and shrink figures.
- Grade 8 Module 3: Similarity In Module 3, students learn about dilation and similarity and apply that knowledge to a proof of the Pythagorean Theorem based on the Angle-Angle criterion for similar...
