Among mathematical sciences, Geometry is the one which has the most especial reference to architecture, and we can, therefore, under the name of Geometry, understand the whole art of Freemasonry. In Anderson's book of constitutions, Freemasonry is frequently called Geometry, and of the latter he said of the whole being of the Order is comprehended in it. Freemasons therefore ought to make themselves intimately acquainted with Geometry. It is not absolutely necessary to be able to deduce all our actions, works, or resolutions from Geometrical principles. — ( 1 Corinthians 3:9-17 )
By this science the architect is enabled to construct his plans, and execute his designs; the general, to arrange his soldiers; the engineer, to mark out grounds for encampments; the geographer, to give us the dimensions of the world, and all things therein contained; to delineate the extent of seas, and specify the divisions of empires, kingdoms and provinces. By it, also, the astronomer is enabled to make his observations, and to fix the duration of times and seasons, years and cycles. In fine, Geometry is the foundation of architecture, and the root of the mathematics.

Biblical Reference
1 Corinthians 3:9-17
9 For we are labourers together with God: ye are God's husbandry, ye are God's building. 10 According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon. 11 For other foundation can no man lay than that is laid, which is Jesus Christ. 12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. 14 If any man's work abide which he hath built thereupon, he shall receive a reward. 15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. 16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? 17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
