Glencoe McGraw Hill 4 Glencoe Geometry,NAME DATE PERIOD. 1 1 Reading to Learn Mathematics,Points Lines and Planes. Pre Activity Why do chairs sometimes wobble, Read the introduction to Lesson 1 1 at the top of page 6 in your textbook.
Find three pencils of different lengths and hold them upright on your. desk so that the three pencil points do not lie along a single line Can you. place a flat sheet of paper or cardboard so that it touches all three pencil. How many ways can you do this if you keep the pencil points in the same. Lesson 1 1, How will your answer change if there are four pencil points. Reading the Lesson,1 Complete each sentence, a Points that lie on the same lie are called points. b Points that do not lie in the same plane are called points. c There is exactly one through any two points, d There is exactly one through any three noncollinear points. 2 Refer to the figure at the right Indicate whether each. statement is true or false D,a Points A B and C are collinear P. b The intersection of plane ABC and line m is point P A. c Line and line m do not intersect m,d Points A P and B can be used to name plane U.

Helping You Remember, 4 Recall or look in a dictionary to find the meaning of the prefix co What does this prefix. mean How can it help you remember the meaning of collinear. Glencoe McGraw Hill 5 Glencoe Geometry,NAME DATE PERIOD. 1 1 Enrichment,Points and Lines on a Matrix, A matrix is a rectangular array of rows and columns Points and.
lines on a matrix are not defined in the same way as in Euclidean. geometry A point on a matrix is a dot which can be small or. large A line on a matrix is a path of dots that line up Between. two points on a line there may or may not be other points Three. examples of lines are shown at the upper right The broad line can. be thought of as a single line or as two narrow lines side by side. Dot matrix printers for computers used dots to form characters. The dots are often called pixels The matrix at the right shows. how a dot matrix printer might print the letter P, Draw points on each matrix to create the given figures. 1 Draw two intersecting lines that have 2 Draw two lines that cross but have. four points in common no common points, 3 Make the number 0 zero so that it 4 Make the capital letter O so that it. extends to the top and bottom sides extends to each side of the matrix. of the matrix, 5 Using separate grid paper make dot designs for several other letters Which were the. easiest and which were the most difficult,Glencoe McGraw Hill 6 Glencoe Geometry. NAME DATE PERIOD,1 2 Study Guide and Intervention,Linear Measure and Precision.
Measure Line Segments A part of a line between two endpoints is called a line. segment The lengths of M N and R,are written as MN and RS When you measure a. segment the precision of the measurement is half of the smallest unit on the ruler. Example 1 Example 2,Find the length of M S,Find the length of R. cm 1 2 3 4 in 1 2, The long marks are centimeters and the The long marks are inches and the short. shorter marks are millimeters The length of S,marks are quarter inches The length of R.
