constant elevation‚ as suggested by the diagram below left. By measuring the net distance traveled in each of two perpendicular directions‚ the lengths of two legs of a right triangle are determined‚ and the hypotenuse of the triangle is the proposed line of the tunnel. By laying out smaller similar right triangles at each entrance‚ markers can be used by each crew to determine the direction for tunneling. Later in this article I will apply Hero’s method to the terrain on Samos. Hero’s

construction of those buildings. Understanding how to solve math problems becomes easier as one learns math terminology. Below is a list of many common math terms and their definitions. Acute angle – An angle which measures below 90°. Acute triangle – A triangle containing only acute angles. Additive inverse – The opposite of a number or its negative. A number plus its additive inverse equals 0. Adjacent angles – Angles with a common side and vertex. Angle – Created by two rays and containing an

above triangle and find the value of B‚ b‚ and c. A. A+B+C=180 B. A+C=48+97=145 C. B=180-145=35 2. Two sides and an angle (SSA) of a triangle are given. Determine if the given measurements produce one triangle‚ two triangles‚ or no triangle at all. Sin B)/5=sin70/7 Sin B/5=0.9397/7 Sin B=0.6712 then B=42 or 138〗 B = 138 is impossible since 138 + 70 = 208 and exceeds 180 B=42 since 42+70 = 112 and less than 180 C = 180 – 112 = 68 There’s only one triangle 3

into four congruent isosceles triangles (Two angles are 45 degree). Square is a special rectangle. 2. Equilateral Triangle An acute triangle with all angles and sides congruent‚ the angle is 60 degree. It is also known as the isosceles triangle with one 60 degree angle. The sum of two sides is greater of the third side and the difference of two sides is smaller than the third one. Each bisector‚ altitude and angular bisector of a side is coincident. Equilateral triangle is a symmetrical figure and

are coprime . A right triangle whose sides form a Pythagorean triple is called a Pythagorean triangle . The name is derived from the Pythagorean theorem ‚ stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2 ; thus‚ Pythagorean triples describe the three integer side lengths of a right triangle. However‚ right triangles with noninteger sides do not form Pythagorean triples. For instance‚ the triangle with sides a = b

Within the sailboats and the waves forms is the shape of triangles. The tops of the houses also have triangular shapes to them. The oval shape of the flying birds resembles the clouds and adds to the skyline a lively repetition that draws the eye towards the lone ship in the distance. As the waves seem to move to
