A * * * on these two lines has 15*2=30 line segments. In addition, except one line segment on the AD line, the other five vertical diagonals have 1+2=3 line segments respectively, so there are 3*5= 15 line segments, so the total * * has 30+. The second question is that it is more convenient to calculate line segments. Horizontally, there are four lines, and each line has five basic line segments, all of which have 1+2+3+4+5= 15, so a * * has 15*4=60 line segments; The examination questions and answers in the final exam of the first volume of junior two mathematics dxb0823 prove that ef⊥bc ∵ad⊥bc in F (known) 26, (14) (1) In order to protect the environment, Xiao Min, an environmental protection team member of a school, collected waste batteries, and collected them on the first day.

The mutual transformation of ...........................'s two kinds of plane graphics and three-dimensional graphics is called folding carton problem-space reduction of plane graphics, and unpacking problem-plane expansion of three-dimensional graphics. The spatial restoration of a plane figure is to give a plane figure, that is, a plane expansion diagram of a three-dimensional figure, so that candidates can restore this plane figure into a spatial figure. Another kind of problem, which is opposite to the above-mentioned folding carton problem, is unpacking, that is, the topic gives a three-dimensional figure, so that candidates can choose an answer that can be folded into a given three-dimensional figure from four flat graphic options. 27 Mathematical Thinking Training Course The sixth grade must belong to peaches and plums (top students) Example 4 As shown in the figure, the area of the rectangle is 35㎝2, the area of the lower left right triangle is 5㎝2, and the area of the upper right triangle is 7㎝2, so the area of the middle triangle (shaded part) is square centimeters. There are several cubes with the volume equal to 1 in the corner, stacked into a three-dimensional figure as shown in the figure below (each cube can move independently, but if the lower cube is removed, the upper cube will automatically fall. Some people want to get rid of some cubes, but how many small cubes can they get rid of at most when the shadows on the wall and the ground remain unchanged under the irradiation of parallel light on the front, top and right? If the area of triangle ABC is 48, what is the area of triangle AFD? In the fourth week, he opened three pipes at the same time and filled a pool of water in 2 hours and 20 minutes.
