In the triangle ABC, ABC is three sides, the square of (a + b) - the square of C = 2Ab, then the triangle is? In the triangle ABC, a, B and C are three sides, the square of (a + b) - the square of C = 2Ab, then the triangle is___________ triangle? How many answers should there be? I wrote right triangle or isosceles triangle or isosceles right triangle, p. I know there must be a right triangle, but I asked if it could be isosceles or isosceles right triangle? If a = B, then the original formula = 2A ^ 2 + 2A ^ 2-C ^ 2 = 2A ^ 2 That is, C ^ 2 = 2A ^ 2, according to the Pythagorean theorem, C ^ 2 = a ^ 2 + B ^ 2, then the equation holds! It may be an isosceles right triangle!

It may be an isosceles right triangle!

The result of this simplification is
A ^ 2 + B ^ 2 = C ^ 2, this is Pythagorean theorem, used to prove the right triangle
What you get is an isosceles right triangle, which is also a special right triangle. Other isosceles triangles can't satisfy this equation
To sum up: filling: right triangle is more accurate and comprehensive

A and B have a number guessing game. They said that the opposite number of a is equal to itself. B said that the absolute value of the largest negative integer of B. what is the value of a + B?

1+1=2
0 has no opposite number, so only 1 is qualified for a
B. The maximum negative integer is - 1 and the absolute value is more than 1

Students a and B play a number guessing game. A says that the absolute value of a is root 2. B says that the arithmetic square root of a number is equal to itself. Please guess the opposite number of A-B is ()

a=±√2
B = 0 or 1
So A-B = √ 2-1 or - √ 2-1 or √ 2 or - √ 2
So the opposite number is - √ 2 + 1 or √ 2 + 1 or - √ 2 or √ 2

A, B and C play a number game: a says that the opposite number of a is the largest negative integer; B says that the absolute value of B is the smallest number; C says that the absolute value of C is the smallest number
On the contrary, the number and absolute value are itself, please guess a + B + C = how much

The largest negative integer is - 1, so a = 1,
The minimum absolute value is 0, so B = 0,
On the contrary, both the number and the absolute value are itself, and the number is 0, so C = 0
So a + B + C = 1 + 0 + 0 = 1
