How to Construct Pascal's Triangle. In Pascal's Triangle, the top row is 1, with the second row just below it containing 1 and 1. To construct each subsequent row, add each pair of numbers, moving from left to right so that each number on a row is the sum of the two numbers just above it, to the right and the left.Put a 1 on both ends of each row.o construct each subsequent row, add each pair of numbers, moving from left to right so that each number on a row is the sum of the two numbers just above it, to the right and the left. Put a 1 on both ends of each row.
One is to use Pythagoras' Theorem and some algebra. This method is illustrated in the answer I gave to Sharon in response to a question she asked last year. The second method uses Heron's formula. Heron's formula shows you how to find the area of a triangle from the lengths of the three sides. Use Heron's formula to find the area A of your triangle. You also know that the area is half the base times the height and since you have a base of 15. A = 1/2 Ã15 Ã height. Solve for the height. I hope this helps,
