Geometry in the real world BY. DILLON PATEL Point Bolton, England is a point because it’s a location on a map and is represented by a point as shown in the picture to the left. A point can be made when two lines intersect. https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact= 8&ved=0CAYQjB0&url=http%3A%2F%2Fwww.lonelyplanet.com%2Fmaps%2Feurope%2Fengl and%2Fbolton%2F&ei=eADdVM_vMIKlgwTD64P4Bw&bvm=bv.85761416,d.eXY&psig=AFQjC NFyw8bX1EjajuvhOfFIGFVWO7PeRg&ust=1423856114979805 Line A road is an example of a line because its never ending and doesn’t have midpoints or endpoints. A line cant be formed when to planes come side by side and touch, between the to planes is a line that is formed. https://www.google.c om/url?sa=i&rct=j&q=& esrc=s&source=images &cd=&cad=rja&uact= 8&ved=0CAYQjB0&url= http%3A%2F%2Filiafoul advand.com%2F%3Fat tachment_id%3D152& ei=4QTdVMrCCYqggS8q4D4Aw&bvm=bv .85761416,d.eXY&psig= AFQjCNF09PGaSQvAk dJZf_4_uqID0iUIJw&ust =1423857243320612 Plane A plane is a platform or area that points and lines can lay on, a plane can be named by the letter it can have or by three points in the grid that aren’t in the same line. https://www.google.com/ url?sa=i&rct=j&q=&esrc=s &source=images&cd=&ca d=rja&uact=8&ved=0CAY QjB0&url=http%3A%2F%2F www.alamancechristiansc hool.org%2Fwarriorbaseball-fieldfundraiser%2F&ei=vQbdV OmjEomjgwSW0oDoCQ& bvm=bv.85761416,bs.1,d.e XY&psig=AFQjCNG2ItR7QJ bodCJgmwL7t9E5sUz67w& ust=1423857724322310 Line Segment The lines on a road are segments because they end and don’t last forever. Segments have two endpoints and two midpoints. Ray http://modernsurviv alblog.com/wpcontent/uploads/20 13/10/bestflashlight-for-ablackout.jpg A flashlight is a ray because it goes from and endpoint and leaves in one direction. A ray has one endpoint and no midpoints because it never ends. Collinear Points This road is a collinear line because the 17 and 527 are on the same road or line. Collinear points are two points on the same line. http://f.tqn.com/y/orlando/1/S/5/U/colonial.jpg Acute angle A pyramid is an acute angle because it is less than 90 degrees. An acute angle is an angle that measures less than 90 degrees. Obtuse angle The pages of a wide open book are obtuse because it measures more than 90 degrees. An obtuse angle measures more than 90 degrees and less than 180 degrees. Right angle The window is a right angle because it ,measures 90 degrees in a corner. A right angle is and angle that measures exactly 90 degrees. Perpendicular lines The cross is perpendicular because the four corners equal right angles. Perpendicular lines make 90 degrees. Complementary Angles The corner of a white board measures to 90 degrees. A complementary angle is a right angle. Supplementary angles The wire is a supplementary angle because it’s a straight line. Supplementary angles equal 180 degrees. Right Triangles This picture is a right triangle because it has a 90 degree angle. A right triangle is a triangle with one 90 degree angle and two acute angles. Vertical Angles The scissors are vertical because once they are open there are two different angles across from each other. A vertical angle is a angle they shares only a point with another angle nothing more. Acute Triangles This pie slice is acute because it has all angles that measure less than 90 degrees. A acute angle has no angle bigger than 90 degrees. Obtuse Triangles This is a obtuse angle because of the one large and two acute angles. An obtuse angle has a larger than 90 degree angle and two acute angles. Equilateral Triangles This ball rack is equilateral because all angles have the same measure. A equilateral has all the same measures no matter how big or small they are all the same. Isosceles Triangles The pie is Isosceles because two of the sides are the same measure. A isosceles triangle has two or more equal sides. Scalene Triangle This triangle is scalene because none of the sides are the same. A scalene triangle has different measures for all angles and sides.
