รูปสามเหลี่ยมมุมฉาก (right, right-a

Right-angled triangle (right-angled, rectangle, right) is one of the corner size inside corner 90° (a right angle) The side opposite the angle of the scene called the hypotenuse is the longest side in a triangle. The other two sides are called cathetus. The length of the sides of a right triangle are related to each other according to the theorem, p Tana korat, that is, the square of the length of the hypotenuse. C is equal to the sum of the squares of the cathetus is a brief write b, a2 + b2 = c2 show the additional special right triangle format.

Triangles (right, right-angled, rectangle) with one internal angle measures 90 ° (angle) side opposite the right angle is called. Hypotenuse Which is the longest side of the triangle. The other two sides are called Perpendicular Side lengths of a right triangle relationship between the Pythagorean theorem. That is, the square of the length of the hypotenuse c is equal to the sum of the squares of the perpendicular, a, b written statement as a2 + b2 = c2, see. Special right triangles

A right-angled triangle (right right-angled,,Rectangle) angles are one size 90 ° (right) side opposite the right angle is called the ตรงข้ามมุมฉาก with, which is the longest side of the triangle. The other two sides as war reparations.That is the square of the length of the hypotenuse equals the sum of the squares of the C to the assembled over the scene, aB written summary is A2 B2 = C2 the right-angled triangle.
