This ensemble of printable worksheets for grade 8 and high school contains exercises to identify and draw the points, lines and planes. Exclusive worksheets on planes include collinear and coplanar concepts. Interesting descriptive charts, multiple choice questions and word problems are included in these pdf worksheets.
In two dimensions the graph of a linear equation, either y=ax+b or parametric (x(t),y(t)), is always a straight line, and a point and slope or two points completely determine the line. In three dimensions the graph of a linear equation, either z=ax+by+c or parametric ( x(t), y(t), z(t)), has more freedom, and it can be a line or a plane.
Example 2: x = 3. Is the graph of x = 3 the graph of a line or a plane or a point? Just like above, the answer will depend on the dimensions we are working in. In one dimension, x = 3 is just a point, as in a point on the number line. In two dimensions, the graph is a line, as you can see by rotating the below graph.
The line has only one dimension, and the points that lie on the same line are called collinear points. A line segment is denoted by two points, say AB. Two lines that meet at a single point are called intersecting lines. On the other hand, a plane extends infinitely in two dimensions. The plane has no thickness, and a typical example of a plane ...
Sketch a plane and a line that is in the plane. b. Sketch a plane and a line that does not intersect the plane. c. Sketch a plane and a line that intersects the plane at a point. SOLUTION a. b. c. EXAMPLE 4 Sketching an Intersection of Planes Sketch two planes that intersect in a line. SOLUTION Step 1 Draw a vertical plane. Shade the plane.
For example, a worksheet might ask students to draw a line segment connecting two points and label it. Naming Figures – Students practice using geometric symbols to name figures. They might be given a figure with several points labeled and asked to name all the possible lines, line segments, and rays that can be formed.
