Hurry up, hurry, hurry, hurry

Come on, come on, let's teach you something that works. The easiest: make a pen holder!!

Do you have any glasses at home that you don't use? Or drop the teacup or something, try it, as long as it's heavy enough to hold the pen. Find a nice piece of cloth, or colored paper, and make a dress for the cup.

Kraft paper is also very good, wrap it on the cup and measure it, cut out a suitable piece, and have more joints.

6.Please explain how to make a gizmo!

Homemade Kong Ming lantern (1) Cut into pieces of paper with tissue paper as shown in the picture. Glue one side of the first sheet of paper to the side of the second, then the third, and then the fourth. Glue them together until they form a ball with a diameter of about 60 centimeters.

Kraft paper is also very good, wrap it on the cup and measure it, cut out a suitable piece, and leave an extra centimeter or so at the joint.

Find some glue ,..

8.Gizmo proposed.

"If I have a small achievement, there is no other secret but hard work. ”

Brother, I'm sorry, there's really nothing I can do!

China is very short of water! South-to-North Water Diversion! Save water, of course! Start with the individual, and slowly people will realize it.

The first question must have been wrong! It should be proved that the triangle abo is similar to the triangle cdo to prove: (1) because angle 1 = angle 3, angle cod = angle aob, then 180-angle cod-angle 3 = 180-angle aob-angle 1, that is, angle b = angle d, so triangle abo is similar to triangle cdo

2) Because angle 1 = angle 2

Hurry up and ask your teacher, the first question is wrong, because the two certificates are contradictory.

(1) The CDO is similar to ABO.

Angle 1 = angle 3, angle AOB = angle cod (equal to the apex angle), so the two triangles are similar (2) is obtained from (1), angle b = angle d

Because angle 1 = angle 2, angle bac = angle dae

So the two triangles are similar.

The average weight is 35kg, which means that everyone loses 35 from their weight.

Answer: 0kg, 4kg, -2kg, 1kg, -2kg,

If the area of a sector of 90 degrees is denoted as s1, the area of a rectangle is denoted as s2, and the area of the upper and lower shaded parts is denoted as a and b respectively, then there is 2*s1+a-b=s2

Because the question is set a=b, 2*s1=s2

Write down the length you are looking for as x

Then there is 2*(1 4)*pi*r 2=r*x, which is calculated as x=(pi 2)*r=(pi 2)*(1 cm)=pi 2 cm. =.Centimeter.

That's the idea, I don't know if there's anything wrong with the calculation, you check it.

How happy the old fox must have been when he brought the little fox out with his own strength, every time the family ......All the way to the defense, in the broken bowl on the floor.
