XXIII by the indirect method. If a transversal cuts two straight lines making the alternate exterior angles equal, the two lines are parallel. When two lines in the same plane are cut by a transversal, if the alternate-interior angles are equal, the two lines are parallel. The side AB upon which the triangle is supposed to rest is the base of the triangle. This arrangement of the index is intended to facilitate finding a problem more rapidly, since two or more problems may appear on a page.

A plane figure D formed by a broken line is called a rectilinear figure. The conclusion is false; therefore the supposition is false and must be abandoned. Bisect each of the four right angles formed by two lines bisecting each other at right angles. Two right triangles are equal if the hypotenuse and an acute angle of the one are equal respectively to the hypotenuse and an acute angle of the other. With X as a center and XY as a radius draw a circle, and with Y as a center and the same radius draw another circle, and call one intersection of the circles C.

It has been the purpose to prepare a book that should do even more than maintain the traditions this work has fostered. Let AB be the given line. Modern scholars agree that Euclid's postulates do not provide the complete logical foundation that Euclid required for his presentation. In division the divisor is never zero.

Two triangles are congruent if two sides and the included angle of the one are equal respectively to two sides and the included angle of the other. Plane and solid geometry book lines H and K are each parallel to the line L.

E F Any Plane and solid geometry book of a triangle may be assumed as the base. Draw the plan, using a scale of 4 in. It is attributed to Thales, a Greek philosopher. Draw a triangle of which each side is 1 in.

The following are the most important axioms used in geometry: 1. Such a method of proof is known as the synthetic method, and is the most common of all that are used in geometry.

PROOF Could a and b, upon being produced, meet at some point, as at X, there would be two perpendiculars drawn from the point X to the line m, which is impossible. A line is either parallel to a plane, intersects it at a single point, or is contained in the plane.

In a triangle there can be but one right angle or one obtuse angle. Notions such as prime numbers and rational and irrational numbers are introduced. The science of geometric figures is called geometry. ED parallelogram. An exterior angle of a triangle is equal to the sum of the two opposite interior angles, and is therefore greater than either of them.

PB bisects the angle ABC. Many facts that are stated in arithmetic and algebra are proved in geometry. The opposite angles of a parallelogram are equal.

That which has only position, without length, breadth, or thickness, is called a point. If a line is perpendicular to one of tzo parallel lines, it is perpendicular to the other also. Euclid, rather than discussing a ray as an object that extends to infinity in one direction, would normally use locutions such as "if the line is extended to a sufficient length," although he occasionally referred to "infinite lines".

Any side of a triangle is greater than the difference of the other two sides. Define each. Find the value of x and the size of each angle. Plane geometry treats of figures that lie wholly in the same plane, that is, of plane figures.
