Philosophy of Constructions Constructions using compass and straightedge have a long history in Euclidean geometry. The square root of 200 is 14.142 feet. So the distance squared is equal to 25 plus 1 is equal to 26. 1. Practical Geometry Construction of Quadrilaterals. Proof of Construction: As a result of the construction of the perpendicular at B', m∠A'B'C = 90º, since perpendicular lines meet to form right angles, and a right angle contains 90º. Math Application . It works by first erecting a perpendicular and then drawing the three remaining sides all the same length. The usual construction of the golden proportion. Put the needle on B and make two arcs of the circle c ( B, a). The mathematician, Pythagoras, discovered a relationship between the sides of any right triangle that is now known as the Pythagorean Theorem; he proved that the square of the longest side (the hypotenuse) is equal to the sum of the squares of . There can be many entity collections in a model. Many of the things we see in our daily life resemble the mathematical shapes like circle, quadrilateral, triangle etc. Geometric constructions show properties of a figure through the construction of that figure. Select point A and AB. 1.2 Euclid's construction of the equilateral triangle 5 This example nicely shows the interplay among • construction axioms, which guarantee the existence of the construc- tion lines and circles (initially the two circles on radius AB and later the line segments BC andCA), • geometric axioms, which guarantee the existence of points required for later steps in the construction (the . The diagonal that cuts across the room, and which forms the hypotenuse of the triangles, should be 14.142 feet: 10 2 +10 2 =200.
