The length of one side of a right triangle is 2, and the minimum angle is 25 degrees
If one right side of the minimum angle is 2, the other right side is 2
If the opposite side of the minimum angle is 2, the other right angle side is 2cot25
As shown in the figure, a new figure is made up of four right triangles with sides a, B and C. two different methods are used to calculate the area of the figure
Integral calculation (a + b) &# 178; = A & # 178; + 2Ab + B & # 178; partitioned calculation 4 × AB / 2 + C & # 178; = 2Ab + C & # 178; because it is the area of the same square, so a & # 178; + 2Ab + B & # 178; = 2Ab + C & # 178; sort out a & # 178; + B & # 178; = C & # 178; get a proof of Pythagorean theorem
The side length of a right triangle is 2 cm on one side and 3 cm on the other
Two cases
When 3cm is hypotenuse
The other side is 5 cm long
When 3cm is a right angle side
The length of the other side is √ 13cm
It is known that the length of the hypotenuse of a right triangle is root sign 6. In two right triangle sides, the length of one side is equal to the decimal part of the other side, and the length of two straight sides is calculated
One is the root 2 + 1
The other is the root 2-1
It's very easy to solve. It's not easy to write symbols
The length of two right angles of a right triangle is 1790 and 2850, and the length of the other side is calculated from two angles of 68 ° 22 °
Since it's a right triangle
We don't need angle value, we can use Pythagorean theorem
Square of hypotenuse = 1790 + 2850 = 11326600
Bevel = 3365.5
A right triangle is 23cm long on one side and 34cm long on the other. How long is the third side?
Triangle: a + B = C (C is the longest side)
Root (23m3 + 34m3)
The length of a right triangle is 160 on one side and 125 on the other side
If the sides of length 160 and 125 are right angle sides, then the hypotenuse = 5 times the root sign 1649
If the side of length 160 is beveled and the side of length 125 is right angle, then the other right angle side = 5 times 399
The length of each side of a right triangle is 3 and 4. What is the length of the other side
It is known that the lengths of two sides of a right triangle are 4 and 3 respectively. Find the other side
It's five
Three sides 3,4,5 are fixed numbers of Pythagorean theorem for teaching triangles
Sorry, I didn't see root 7. I saw root 7
Downstairs, your answer is correct
(lost face, gone with the wind)
In a right triangle, an acute angle is 45 degrees, one right angle is 10 cm long, and the other right angle is 45 degrees long
10 cm, because it is a right triangle, and an acute angle is 45 degrees, then the other angle is also 45 degrees, that is, isosceles right triangle, so the two right sides are equal length, are 10 cm
In a right triangle, an acute angle is 45 degrees, one right side is 10 cm long, the other is () cm long
10
