Divide a right triangle into a right triangle and an obtuse triangle with a line

Divide a right triangle into a right triangle and an obtuse triangle with a line

The line passes through an acute vertex of the right triangle and any point on the opposite side of the acute angle

How to draw a line into two obtuse angles in an obtuse triangle

Draw a straight line from the starting point of the acute angle and draw it in the triangle

Is the center line on the right side of an isosceles right triangle an angular bisector

The center line on the right side of an isosceles right triangle is not an angular bisector
The center line on the hypotenuse of an isosceles right triangle is the bisector of a right angle

What are the properties of the bisector of a right triangle

The bisector of the right angle of a right triangle has no special property, only the general property of the bisector. The center line on the hypotenuse of a right triangle is equal to half of the hypotenuse

Right triangle angle bisector Urgent need

Do not bisect right angles
Property of angular bisector: let ad be the angular bisector of △ ABC, then BD / CD = AB / AC
This is a very useful theorem, now junior high school textbooks do not seem to say

There are the following statements: 1) the bisector, center line and height of a triangle are all line segments; 2) a right triangle has only one height; ③ The middle line of the triangle may be outside the triangle; 4) the height of the triangle is inside the triangle and intersects at a point A. 1 B. 2 C. Three D. Four

Only (1) is correct
(2) There are three tall ones;
(3) : the midline cannot be on the outside;
(4) : high to a point, but may be outside
Choose a

Is the bisector on the hypotenuse of a right triangle equal to the center line of the hypotenuse

not always

Three midlines, three angular bisectors, and three heights of a triangle____ The intersection of the three heights of a right triangle is____ ; obtuse angle three A shape has two heights that lie outside the triangle

The three midlines, the three bisectors and the three heights of the acute triangle are all in the interior of the triangle;
The intersection of the three heights of a right triangle is the right vertex of the right triangle;
An obtuse triangle has two heights on the outside, one on the inside, and their intersection on the outside

If the height of the hypotenuse of an isosceles right triangle is 1, then its waist length is

√2
Three sides of isosceles right triangle 1:1: √ 2
Then, if there is height, it will form an equal right angle waist triangle, so waist length = √ 2, height = √ 2

As shown in the figure, take the hypotenuse of the first isosceles right triangle as the waist of the second isosceles right triangle, take the hypotenuse of the second isosceles right triangle as the waist of the third isosceles right triangle, and so on. If the hypotenuse of the ninth isosceles right triangle is 16 root sign 3, what is the length of the hypotenuse of the first isosceles right triangle The answer is root 3 But how is the root 3 calculated?

If the waist length of the first isosceles right triangle is a, then the waist length of the second. Is (√ 2 ·) Ψ · a
2. A)
The waist length of the fourth was (√ 2) 3 · a
.
The waist length of the ninth isosceles right triangle is the product of the eighth power of √ 2 and a
ν (√ 2) ^ 8 · a = 16 √ 3, a = 3
