Number added to a code (such as a bar code or account number) to derive a further number as a means of verifying the accuracy or validity of the code as it is printed or transmitted.
An equilateral triangle has the following properties. 1  Equilateral triangles have three equal side lengths. 2  Equilateral triangles also have three equal angles of 60 degrees. 3  They also have three equal altitudes.  Is the height of an equilateral triangle equal to its side 1  length. The height is equal to side/2 x  â3.
an equilateral triangle has three sides of equal length and three equal angles an isosceles triangle has two sides of equal length and two equal angles a scalene triangle has no sides of equal length and no equal angles a right angle triangle has one angle that is 90 degreesan obtuse triangle has one angle larger than 90 degrees an acute triangle has angles that are all less than 90 degreesthe longest side of a right angle triangle is called the hypotenuse it is always found opposite the right angleind information related to equilateral triangles isosceles triangles scalene triangles obtuse triangles acute triangles right angle triangles the hypotenuse angles of a triangle and more
