The sum of two adjacent sides of a parallelogram is 15 cm. How many cm is the perimeter of the parallelogram? It's a list
Is it a primary school student? First of all, the opposite sides of a parallelogram are equal. The perimeter of a parallelogram is the same as that of a rectangle, which is 2 times (one side + the adjacent side of this side). Now we know (one side + the adjacent side of this side), so the perimeter is 15 times 2, which is 30cm. Remember my above formula. If you don't understand, ask me again
The perimeter of a parallelogram is 80 cm, one of which has a bottom edge of 15 cm, and its height is 10 cm. How many cm is the height of the other?
Because one side is 15, the other side is 80 / 2-15 = 25
Area of parallelogram = 15 * 10 = 25 * h
The height of the other one is h = 150 / 25 = 6cm
The length of two adjacent sides of a parallelogram is 15 cm and 10 cm respectively. What is its circumference? It will be handed over tomorrow
15 + 15 + 10 + 10 = 50, thank you, but you have to make up for your lessons
Is the formula of parallelogram area: half of diagonal product = s correct? If so, how is it derived?
This formula only conforms to any quadrilateral whose diagonals are perpendicular to each other. In parallelogram, only diamond and square conform. I hope my answer is useful to you. Have a good time
Diagonal formula of parallelogram
The sum of squares of two pairs of intersecting lines of a parallelogram is equal to the sum of squares of four sides,
The formula for finding the diagonal of parallelogram
The distance and angle of two opposite sides of a parallelogram are known
How to find the diagonal length?
Using the simplest algorithm
If the two diagonals of parallelogram are known to be 12 and 10, the range of M can be obtained
A B
E
C D
BC = 10 ad = 12
And the diagonals of the parallelogram are equally divided with each other
AE=ED =1/2 AD=6 BE=EC=1/2 BC=5
I don't know if M is the side length
Right
Then the third side of the triangle is greater than the difference between the two sides
Less than the sum of the two sides
That is, 6 + 5 is greater than m and 6-5
If the two diagonals of a parallelogram are 8 and 10, then its side length cannot be a.7b.9c.10
∵ parallelogram
The diagonals are divided equally
∴8÷2＝4 10÷2＝5
∵ in a triangle, the sum of any two sides is greater than the third side
However, B.9 and C.10 are not available
Given that point P of a (1,1,1), B (3,3,3) is on the x-axis, and the absolute value PA = the absolute value Pb, then the p-coordinate
(0,1.5,1.5)
It is known that the length of one side of a parallelogram is 12, and the length of its two diagonals may be ()
A. 8 and 14b. 10 and 14C. 18 and 20d. 10 and 34
A. If half of the two diagonals are 4, 7, ∵ 4 + 7 = 11 < 12, ∵ can not form a triangle, so this option is wrong; if half of the two diagonals are 5, 7, ∵ 5 + 7 = 12, ∵ can not form a triangle, so this option is wrong; if half of the two diagonals are 9, 10, ∵ 9 + 10 = 19, ∵ can form a triangle, so this option is correct; if half of the two diagonals are 5, then this option is wrong , 17, ∵ 5 + 12 = 17, ∵ can't form triangle, so this option is wrong
