This blog is an interactive math classroom where my students will be engaged in answering questions pertaining to my lessons and post comments about other students' comments. This blog will serve as an online learning experience for my self and my students. Parents are also encouraged to participate by providing reflective comments about this blog.

Honors Geometry Questions and Summaries
Honors Geometry students, post your questions and summaries here.
G. Gutierrez 3rd The main idea of today's class period was to briefly review our notes and summaries to prepare for the exam we had to take. The exam consisted of challenging our knowledge and accrediting how much we actually learned in this section of our curriculum.
Today in class we learned about rigid transformations. I learned there is 3 basic transformations. We have reflections, rotations, and traslations. I also learned that an isometry is a transformation that preserves lenghts. I also learned that isometries preserve their angle measures, parallel lines, and distance between points.For example if we have two squares with an area of 10 we know they are isometry because they preserve the same measures.
A reflection is a A. A transformation that flips a figure across a line B. A transformation that turns a figure around a point C. A transformation that slides each point of a figure the same distance in the same direction

An isometry is a transformation that preserves lengths, angle measure, parallel lines and distance between points. True or False?

ReplyDeleteWhat are the coordinates of points (4,3) and (7,3)when they are reflected across the x-axis?

C. A transformation that slides each point of a figure the same distance in the same direction
What are the new coordinates of points A(1,5), B(2,3),C(4,2)and D(4,6)when rotated 180 degrees counterclockwise about the origin?
