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.
Best Answer: Draw a picture of your triangle. For all of these triangles, you are given SSA (side-side-angle). You need to find the height of the triangle to see if one of the sides reaches to make a complete triangle. If the side is shorter than the height, then a triangle is not formed.If the side is longer than the height, then two triangles are formed.or all of these triangles, you are given SSA (side-side-angle). You need to find the height of the triangle to see if one of the sides reaches to make a complete triangle. If the side is shorter than the height, then a triangle is not formed.
