If the lengths of the two sides of a right triangle are 3 and 4, then the length of the third side is () A. 5 B. 4 C. Seven D. 5 or Seven

Let the third side be X
(1) If 4 is a right angle side, then the third side x is an oblique side
32 + 42 = X2, so x = 5
(2) If 4 is an oblique side, then the third side x is a right angle side
32 + x2 = 42, so X=
7，
So the length of the third side is five or five
7．
Therefore, D

The two right sides of a right triangle are 6cm and 8cm respectively, and the hypotenuse is 10cm A. 2.4 cm B. 4.8 cm C. 6 cm D. 1.2 cm

Let the height on its bevel be x cm,
10x÷2=6×8÷2，
10x=48，
x=4.8；
A: its height on the bevel is 4.8 cm;
Therefore, B

Given that the right angle side of an isosceles right triangle is 1 meter long, find the third side

Because the two base angles of an isosceles triangle are equal
A right triangle has a 90 degree angle
So the top angle of the isosceles right triangle is 90 degrees, and the two base angles are 45 degrees
So the two right angles are one meter
So the third side is under the root sign (square of 1 + square of 1) = root 2

Given that two sides of a right triangle are 3 and 4 respectively, the area of the square with the third side as the side length is more

1--, two right angles = 3 / 4, hypotenuse = 5; the area of the square with the third side as the side length = 5 * 5 = 25;
2 --, a hypotenuse 4, a right angle side 3, the other right angle side = root (4 * 4-3 * 3); the area of the square with the third side as the side length = 4 * 4-3 * 3 = 7;

Given the length of two sides of a right triangle, find the length of the other side A right triangle. Given the hypotenuse a = 25cm, height B = 3cm, find out how many centimeters the other right angle side C equals

The problem of Pythagorean theorem is very simple
The square of a plus the square of B is equal to the square of C
The question is:
∵ when the slope a = 25cm and the height B = 3cm
The square of C = the square of a - the square of B
=The square of 25 - the square of 3
=616
∴c=√616

The hypotenuse of a right triangle is 7cm long, and one right side is 1cm longer than the other?

Let the short right angle side be x, then the other right angle side will be x + 1. Then, using Pythagorean theorem, we have x ^ 2 + (x + 1) ^ 2 = 7 ^ 2
And then we can use the root formula to solve it

A right triangle, the length of the two right sides is 14 cm, the ratio of length is 3; 4, the length of the longer right angle side is () cm, The length of the shorter right angle side is () cm. Then the question above is: given that the third side is 10 cm long, what is the height of this side?

A: the shorter right angle side is 6cm, the longer right angle side is 8cm; the height on the bevel side is 4.8cm
The sum of the two right angles is 14, and their ratio is 3:4. Then, divide 14 into 7 parts, the short side accounts for 3 parts, and the long side accounts for 4 parts, that is, the short side = 14 * 3 / 7 = 6, and the long side = 14 * 4 / 7 = 8. Therefore, the area of the triangle is obtained as 6 * 8 / 2 = 24
If the area is calculated by the slope and the height on it, it is 10 * H / 2 = 24, and the solution H = 24 * 2 / 10 = 4.8. Therefore, the height on the bevel is 4.8cm

The length of the two right angle sides of a piece of right triangle cardboard is 21 cm and 14 cm respectively. How many centimeters should be drawn on the two right sides after reducing by 1:7? (scale) Calculate and draw the figure

A right triangle, the two sides adjacent to the right angle are 32 and 24 respectively. To find the length of the hypotenuse, do not use the Pythagorean theorem

If the height of the hypotenuse is x, there will be two more triangles,
The length of the bottom edge is 3 / 4x + 4 / 3x,
Use the same area,
That is 25 / 12 * x * x = 32 * 24,
x=96/5,
25/12*96/5=40
The length of the bottom edge is 40

Pythagorean theorem: if the length of two right angles of a right triangle is 9,40, what is the length of the hypotenuse?

9*9+40*40=1681=41*41
So the length of the hypotenuse is 41

If the lengths of the two sides of a right triangle are 3 and 4, then the length of the third side is () A. 5 B. 4 C. Seven D. 5 or Seven
