Geometry in the Real World By: Alex Jantz Block: 2a

Point The game connect the dots has a series of points. AWESOME!
A point names a location and has no size!!!!!
Line (Segment) The tops of telephone poles are line segments. OH YEAH! A line segment is the part of a line consisting of two end points and all the points in between.
3.
Plane The scrabble board can be considered a plane that is withheld inside of four points which would be the corners of the boards rim. NUH- UH! A flat surface that has no thickness and extends forever
4.
Angle If you notice, the legs come up to an end point, and make an acute angle. OH MY! An angle is a figure formed by two rays, or sides, with a common end point.
5.
Perpendicular Lines If there is a vertical stop light on a horizontal pole, then they create perpendicular lines. VERY INTERESTING! Perpendicular lines are two intersecting lines that form two right angles.
6.
Parallel Lines This photo has 5 sets of parallel linesâ€¦ The metal that makes up the track itself is the best example. COOL! Parallel lines are lines that are always the same distance apart and will never meet.
7.
Triangle There are triangles surrounding the triangle door. Like, Totally, Red, Man A triangle is a closed plane figure having three sides and three angles.
8.
Right Triangle This sign forms a right triangle with the wall. WOWEE!!!! A triangle that has one right angle.
9.
Pentagon Notice how the buildings form a pentagonal shape. CRAZY! a polygon having five angles and five sides.
10.
Hexagon If you notice, the wires create hexagons in the pattern. INTERESTING!!! a polygon having six angles and six sides.
11.
Square The top face is a square. COOL, COOL, COOL!!! a rectangle having all four sides of equal length.
12.
Rectangle This picnic table has multiple different rectangles inside of it. THATâ€™S AWESOME! a parallelogram having four right angles.
13.
Trapezoid The actual bag is in the shape of a trapezoid. Can you see it? I CAN NOT BELIEVE IT! a quadrilateral plane figure having two parallel and two nonparallel sides.
14.
Parallelogram This building has a lower level(biggest) shaped like a parallelogram. ARE YOU SERIOUS?!?! quadrilateral having both pairs of opposite sides parallel to each other.
15.
Circle This bottle cap, and all other bottle caps, form a circle. HOLY MOLY!!! a closed plane curve consisting of all points at a given distance from a point within it called the center.
16.
Cylinder All canned food cans form the shape of a cylinder. POSITIVILUTELY CRAZY! a surface or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes.
17.
Sphere Bouncy balls and sport balls( excluding footballs) all form spheres. Crazy, huh? a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center.
18.
Rhombus This pool rack forms a great example of a rhombus. GROOVY! an oblique-angled equilateral parallelogram; any equilateral parallelogram except a square.
19.
Isosceles Triangle This does not mean that I am a fan of the Yankees, it is just an example of an isosceles triangle. ROCKINâ€™! A triangle with at least two congruent sides.
20.
Scalene Triangle The triangle formed in this spider web is a scalene triangle. None of the sides are congruent to each other. A triangle with no congruent sides.
