This document discusses the concept of symmetry by showing how shapes can be cut into two equal parts along a line. It demonstrates that a line of symmetry exists when a shape can be folded along that line, with the two halves being identical mirror images. The document asks students to identify lines of symmetry for different shapes, and defines symmetry as dividing a solid shape such that one part is the mirror image of the other.

3D Shapes - Properties of 3D Shapes
This document introduces 3D shapes by defining their key components of faces, edges, and corners/vertices. It explains that faces are flat or curved surfaces, edges are where two faces meet, and corners are where edges meet. Common 3D shapes are then described based on their number of faces, edges, and vertices, such as cylinders having two circular faces and one curved face, pyramids having three faces with two circles as the base, and cubes having six faces, twelve edges, and eight vertices. The document encourages reviewing properties of 3D shapes and staying safe.
Symmetry Presentation By Manali
This document discusses different types of symmetry found in nature, architecture, art, religious symbols, and music. It provides examples of line symmetry seen in leaves, snowflakes, and butterflies. Architectural symmetry is seen at various scales from overall building designs to individual elements. Symmetry is also used in art forms like beadwork and furniture as well as religious symbols like the Star of David. In music, symmetry has been used as a compositional constraint and in concepts of permutation and invariance. Rotational symmetry makes an object look the same after certain rotations and examples include objects with order 3 and order 6 rotational symmetry.
Symmetry PowerPoint
This document discusses symmetry and how it relates to shapes. Symmetry refers to when one half of a shape is a mirror image of the other half along a line. The document asks questions about identifying lines of symmetry in different images and determining how many lines of symmetry various shapes possess.
Symmetry In Math
There are several basic types of symmetry including line symmetry, rotational symmetry, translational symmetry, reflective symmetry, and glide reflective symmetry. Symmetry can be seen in art, nature, mathematics and other areas. The document discusses these types of symmetries and provides examples like kaleidoscopes, wheels, and shapes to illustrate symmetrical concepts. Exercises are suggested to help understand symmetry further such as folding paper or moving shapes on a plane.
Line symmetry
Line symmetry is the most common type of symmetry where an object can be folded along a central line so that one half is an exact mirror image of the other. Examples of objects that exhibit line symmetry include many creatures, plants, human faces, bodies, letters of the alphabet, and artworks which can be folded along a central line to form two congruent mirror images. Line symmetry is found throughout nature and in human-made objects.
Equal Parts
This document discusses equal parts of a whole using examples of splitting cookies. It explains that for a fair share, each part must be the same size. It then lists different numbers of equal parts (halves, thirds, fourths, etc.) and the name given to each individual part based on the number of total parts the whole was divided into (e.g. if divided into thirds, each part is called a third). The document provides instruction on a video and quiz about fractions as well as math problems and an exit ticket involving naming parts of shapes.

Math Spectacular Symmetry for Year 2 students.ppt
Symmetry refers to shapes or patterns that are reflected across a line or mirror such that the reflected shape is identical to the original shape in terms of size and distance from the mirror line. There are two main types of symmetry: reflective symmetry, where one half of a shape is a mirror image of the other half across a line of symmetry, and line symmetry, where a shape can be folded along multiple lines and have the two halves match exactly. Real-world objects often exhibit symmetry, and the document provides examples of symmetrical patterns and shapes for children to identify instances of symmetry.

TechMathI - 6.2 - Similarity examples
Similar figures are two-dimensional shapes that have the same shape but can differ in size. To be similar, the corresponding sides of the figures must be proportional, meaning they differ by a constant scale factor. Similar figures have the same angle measures but different side lengths. Problems involving similar figures can be solved by identifying the scale factor between corresponding sides and using proportional reasoning.
Ratios, proportions, similar figures
1) Ratios and proportions are used in many areas including map reading, scale drawings, and solving problems.
2) A ratio compares two quantities by division, and ratios that make the same comparison are equivalent ratios. Proportions are equations that state two ratios are equal.
3) Similar figures have the same shape but not necessarily the same size, with corresponding angles being congruent and corresponding sides forming equivalent ratios. Ratios and proportions can be used to solve for unknown sides or quantities in similar figures.

Radial symmetry
Radial symmetry is a type of balance where parts of an object are arranged around a central point. There are three types of balance: radial symmetry, mirror/bilateral symmetry, and asymmetry. Radial symmetry is seen in both natural objects like snowflakes and human-made objects like mandalas, kaleidoscopes, and rose windows in cathedrals. To create radial symmetry, a circle is divided into equal sections and the same pattern is repeated in each section.

Pythagorean Relationship 1
Pythagoras was a Greek mathematician who lived around 2500 years ago. He founded a secretive scientific and religious society in southern Italy. Pythagoras discovered that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the two legs, which is known as the Pythagorean theorem. The Egyptians had previously used this relationship, without realizing it was a mathematical rule, by recognizing that the sides of a 3-4-5 triangle formed a right angle.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
