How to draw square with square root 5 in 4x4
Radical 5 = √ 2 ^ 2 + 1
Select 2 grids on the left side of the bottom edge and 1 grid on the left side vertically. Connect to get √ 5
Draw a square with an area of 5 on the square of 4 times 4
The side length of a square with an area of 5 is √ 5
（√5）^2=2^2+1^1
Draw the diagonal line of two squares as the side length
A square with an area of 10 square centimeters is made by using a 4 × 4 square grid, and then the real number is represented on the number axis 10 and − 10．
A is-
10, B is
10．
Draw a square with an area of 10 square centimeters in a four by four grid Can you draw a picture? I don't understand
Establish a 4 × 4 coordinate system
Take the lower left corner as the (0,0) point, I suggest you draw a picture and look at it
In order to square the area of 10 square centimeter, that is to get the square root 10, so, solve the side length on the line
1×1+3×3=10
Therefore, the side of each radical must be a right triangle with right angles of 1 and 3
By connecting (0,1), (1,4), (4,3), (3,0) respectively
As shown in the figure, in the 8X8 square grid, the side length of each small grid is 1. Please draw an isosceles triangle in the grid to make its area 10 Draw an isosceles right triangle
Bottom = 4, height = 5
Master, how to draw an isosceles triangle with a length of 2 and an area of 6 on a square paper?
If the bottom is 2, then the height is 3, the square edge is 1, and the diagonal is root 2. It is obvious how to draw it, but it is oblique. If you set the square side length as root 2, you can draw a positive one
How to draw an isosceles triangle with side length 2, root 2 and area 6 on the square paper with unit 1
First draw a square of length 2, and then connect its diagonals. The diagonal is 2 and the root is 2
Then draw two adjacent sides as two squares. From their common vertex, connect the opposite vertex respectively, and make two diagonal lines,
In a square grid, draw a square with an area of 10
Because the area is 10, the side length is root 10
1^2+3^2=10
Therefore, the hypotenuse of a right triangle whose side length is 1 lattice and 3 lattice is root 10
And then just paint like I did
ABCD is a square. Because my line is not the same width, it doesn't look like it
ABCD is the square you want
Draw a line segment with the root of ten on the square of 3 times 3, and draw a square with area of 5 on the square of 5 times 5 Can you attach a picture? The square at the back is 4 times 4
The square area of the two bevel sides is 5
