Formulate the properties of a right-angled triangle.

There are many properties of a right-angled triangle. Let’s start with the sum of the sharp corners.

1. The sum of the acute angles of a right-angled triangle is 90 °.

The same property related to corners:

2. The leg, lying opposite an angle of 30 °, is equal to half of the hypotenuse.

The hypotenuse property sounds like this:

3. The hypotenuse of the right-angled triangle is larger than each of the legs.

4. Two heights of a right-angled triangle coincide with its legs.

5. The median of a right-angled triangle, drawn from the vertex of the right angle to the hypotenuse, is the radius of the circle circumscribed about this triangle.

Described circle property:

6. The center of the circumscribed circle of a right-angled triangle lies in the middle of the hypotenuse.

And the main one is the Pythagorean theorem. In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.

c ^ 2 = a ^ 2 + b ^ 2.
