2. Parallel Lines Man-Made • Parallel Lines are coplanar lines that do not intersect. • The top-right picture is the man-made version of parallel lines: lines from notebook paper. • The bottom-right picture shows a piece of banana with parallel lines that do not intersect. • In a textbook we could see an example of parallel lines like this: Natural

3. Point • In geometry, a point has no point, but has position. • The picture on the top-right shows a point in a man-made version: the Target sign. • The bottom-right picture shows a point in a natural form: a mole on your skin. • In a textbook we could see an example of a point like this: Man-Made Natural

4. Pythagorean Triple Man-made • Pythagorean Triple is 3 positive integers a, b, c, such as a2 + b2 = c2. • The top-right picture is a women-made version of a Pythagorean triple because I made the 3,4,5 right triangle. • The bottom-right picture shows a Pythagorean triple in a natural form: stair case steps make a right triangle. • In a textbook we could see an example of a pythagorean triple like this: Natural The smallest and best-known Pythagorean triple is

5. Fractal • A fractal is an object or quantity that displays self-similarity, in a somewhat technical sense, on all scales. The object need not exhibit exactly the same structure at all scales, but the same "type" of structures must appear on all scales. • The top right picture is a picture of a shape poster board in a classroom. This is an example of a man made fractal object. • The bottom right picture is a leaf that represents a fractal natural object. • In a textbook we could see an example of a fractal like this: Man-Made Natural

6. Chord • In plane geometry, a chord is the line segment joining two points on a curve. • The top right picture is a picture of a math spin wheel which is an example of a man made chord, because two points join in a curve. • The bottom left picture is the cross-section of an orange. This is an example of a natural chord where two points join in a curve. • In a textbook we could see an example of a chord like this: Man-Made Natural

7. Cube • The cube is the platonic solid. It is composed of six square faces that meet each other at right angles and has eight vertices and 12 edges. • The top right picture is of a die. This is an example of a cube because it has 6 faces, 8 vertices, and 12 edges. • The bottom right picture is a bell pepper. The bell pepper has 6 faces, this represents a natural cube. • In a textbook we could see an example of a cube like this: Man-Made Natural

8. Ray • A ray is a part of a line that begins at a particular point (called the endpoint) and extends endlessly in one direction. A ray is also called half-line. • The top right picture is of the hands on a clock. The hour hand is an example of a ray because it starts at a point and can go on infinitely. • The bottom right picture is of a leaf with veins that start at one point and extend out. • In a textbook we could see an example of a ray like this: Man-Made Natural Made

9. Pentagon • A pentagon is a five-sided polygon. • The top right picture is of a soccer ball that has a pentagon shaped figure stitched on. • The bottom right picture is of a cross-section of an okra that is a shape of a pentagon on the inside (white part) and around outer edge (green part). • In a textbook we could see an example of a pentagon like this: Man-Made Natural Made

10. Ellipse • An ellipse isa plane curve that results from the intersection of a cone by a plane in a way that produces a closed curve. It has 2 focal points . • The top right picture is of the control buttons on a microwave. • The bottom right picture is a pinto bean in the shape of an ellipse around the edge. • In a textbook we could see an example of an ellipse like this: Man-Made Natural Made

11. Prism Man-Made • A solid figure whose bases or ends have the same size and shape and are parallel to one another, and each of whose sides is a parallelogram. • The top-right picture is a picture of a box. This box is an example of a prism because it has two same size and shape bases that are parallel to each other • The bottom-right picture is a picture of a pepper. The pepper is an example of a prism because it has two same size and shape bases that are parallel. • In a textbook we could see an example of a prism like this: Natural

12. Rectangle Man-Made • A 4-sided polygon where all interior angles are 90° • The top-right picture shows a picture of a ceiling tile. This is an example of a rectangle because it is a 4-sided polygon where all interior angles are 90°. • The bottom-right picture shows a picture of tree trunk. This is an example of a rectangle because it is a 4-sided polygon where all interior angles are 90°. • In a textbook we could see an example of a rectangle like this: Natural

13. Right Angle Man-made • An angle whose measure is exactly 90° • The top-right picture shows a picture of a shelf. This is an example of a right angle because it has a 90°. • The bottom-right picture shows a picture of tree branches. This is an example of a right angle because it has a 90°. • In a textbook we could see an example of a right angle like this: Natural
