# Symétrique ---- ## Symmetrical /sɪˈmetrɪkl/ - Symmetric /sɪˈmetrɪk/ --- # Les points C', D' et E' sont les images des points C, D et E par la translation de vecteur $\overrightarrow{AB}$ ---- ## The points C', D' and E' are the images of C, D and E under the translation of vector $\overrightarrow{AB}$ --- # Moving each point perpendicularly across a straight line (known as the Axis of Reflection)- as far into the other side of the given axis- as the distance from the original point to the axis of reflection ---- ## In plane geometry, reflection across any line --- # The two geometric objects have the same size and shape ---- ## Two geometric objects are said to be congruent /ˈkɒŋɡruənt/ --- # One object can be obtained from the other via a sequence of transformations including rotations, reflexions, translations and dilatations ---- ## Two geometric objects are said to be similar --- # If two triangles are similar ---- ## The ratios of corresponding sides agree --- # Symétrique par rapport à l'origine ---- ## Symmetric about the origin - Symmetric across the origin - Symmetric with respect to the origin <style> .slides {background-image:url("https://raw.githubusercontent.com/tremulotmaths/latex/master/von_koch_transparent.png");} .slides h1 {padding:2em; font-family:Arial; background-color:#133E29; opacity: 0.9;color:white; font-size:1em!important;} .slides h2 {background:#131750 ; opacity: 0.9;padding : 2em 0.2em; color:white; font-size:1em!important;} .slides h4 {margin-bottom:1.5em} </style>
