Four congruent right triangles with side lengths of a, B and C (C is an oblique side) are assembled into a square as shown in the figure. This is to verify the Pythagorean theorem by using area knowledge!

c^2=4*(1/2)*a*b+(b-a)^2=a^2+b^2
(the area of a large square is equal to the area of four triangles plus the area of a small square)

In this paper, we prove a graph which can prove Pythagorean theorem by using two right angle side lengths AB, oblique side C and isosceles right triangle with right angle side length C

As shown in the figure: three right triangles form a trapezoid, calculate the area
(a+b)(a+b)/2=ab/2+ab/2+c²/2
a²+2ab+b²=2ab+c²
a²+b²=c²

An angle of 47 degrees, a 90 degrees to find the degree of angle 1, angle 2, angle 3

Angle one 47 ° angle two 90 ° angle three 43 degrees

A right triangle, known two right angle sides a and B, find the degree of one of the angles a

Tana = A / B, a = arctan (A / b), anti trigonometric function

In a right triangle, angle one is equal to 90 degrees, angle two is four fifths of angle three, and angle three is equal to () degrees To process

Angle two is 40 degrees and angle three is 50 degrees

What is the rule of the degree ratio of the three angles of a right triangle? Given that the ratio of the three angles of a triangle is 1:4:5, try to explain that the triangle is a right triangle. What if it is 2:4:6? What are the rules you found

1. Prove: when the ratio of three angles of a triangle is 1:4:5, let its three inner angles be x, 4x, 5x respectively. ∵ x + 4x + 5x = 180 degrees. (interior angle sum theorem of triangles)

What are the degrees of the three angles of a right triangle ruler

The big ones are 30, 60, 90
It's 45, 45, small

How to calculate the degree of a right triangle

You can know that a right triangle has a degree of 90 degrees, and then you can calculate the other two

Solution equation: in a right triangle, the degree of the larger acute angle is 5 times that of the smaller acute angle

The minimum angle of 6 times is 90 degrees, so the minimum angle is 90 △ 6 = 15 degrees, and the larger acute angle is 5x = 75 degrees

The ratio of the two acute angles of a right triangle is 5:6. Are the two acute angles () and () degrees? It's not 5:6, it's 5:4

The sum of the two acute angles should be 180-90 = 90 degrees. Divide the 90 degrees according to the ratio of 5:4, so the two angles are 50 degrees and 40 degrees
