In a right triangle, the length of two sides is known. Find the third side I don't know what kind of edge is known That one is a right angle side! It's all wrong at 3-25 11:30

We can use the Pythagorean theorem
Three strands, four strings and five strings
The square of a + the square of B = the square of C

Given the two sides of a right triangle, how to find the third side? A right triangle is known Bevel 6 bottom 1.5 seek height? How to find the third side?

a²+b²=c²
1.5²+b²=6²
b²=135/4
B = 135 / 2 of the root

A right triangle has the length of its height and base. How to find the length of the other side? Height 40 cm, bottom 30 cm, the other side? How to find

30 square plus 40 square equals 2500
The square root of 2500 is 50
a^2+b^2=C^2
Pythagorean theorem, C is the hypotenuse
It is also called Pythagoras theorem

It is known that the length of the hypotenuse of a right triangle is C, and the lengths of the two right angles are a, B (a) respectively

a: C = (radical 5-1) / 2
b/a=c/b
b^2=ac
In a right triangle,
a^2+b^2=c^2
a^2+ac-c^2=0
(a/c)^2+(a/c)-1=0
A / C = (radical 5-1) / 2

For a right triangle, its hypotenuse is C, and the length of the other two sides is a, B

S=1/2*A*B

It is known that the length of the hypotenuse of a right triangle is C, and that of the two right angles is a, B (a)

According to the meaning of the title, it is in the form of a ^ 2 + B ^ 2 = C ^ 2
And a / b = B / C, that is, B ^ 2 = a * C. if we put this formula into the form, we can get a ^ 2 + A * C = C ^ 2, and then divide both sides by C ^ 2 at the same time to get: (A / C) ^ 2 + A / C - 1 = 0
If a / C is regarded as a number x, we will get a quadratic equation of one variable, x ^ 2 + X-1 = 0. There should be no problem in solving this equation, right? The value of X will be OK

If the lengths of the two right angles of a right triangle are a, B, the height of the hypotenuse is h, and the length of the hypotenuse is C, then the shape of the triangle with C + H, a + B, h as the sides is () A. Right triangle B. Acute triangle C. Obtuse triangle D. The shape cannot be determined by the size of a, B, C

∵ a, B are the two right sides of a right triangle
∴a2+b2=c2
And ∵ h is the height of the slant, C is the length of the slant
∴ch=ab
∴h2+（a+b）2=h2+a2+b2+2ab=h2+c2+2ch
And (c + H) 2 = C2 + 2CH + H2
∴h2+（a+b）2=（c+h）2
A triangle is a right triangle
Therefore, a

The formula of the oblique side length of a right triangle Bottom edge 0.875 long side 1.52

According to Pythagorean theorem
Beveled edge 2 = 0.875? 2 + 1.52
Hypotenuse = (root 123041) / 200

Formula of oblique side length of right triangle Given a right triangle, one side 8 meters, one side 9 meters, find the other long side,

12.04m

If the length of the two right sides of a right triangle is a, B, the length of the hypotenuse is C, and the height of the hypotenuse is h, then there is () A. ab=h2 B. 1 A+1 b＝1 H C. 1 a2+1 b2＝1 H2 D. a2+b2=2h2

∵1
2ab=1
2CH
∴h=ab
C
∴1
H=c
AB
∴1
a2+1
b2=a2+b2
a2b2=c2
a2b2=1
Therefore, C
