points) 1. Write a paragraph describing the relationship between triangles and circles. Be sure to include a description of the different centers a triangle can have. Answer: Angles and points on the circumference of a circle are the same thing. A point on the unit circle is the same as a right triangle formed by a radius to the point and its perpendicular to the x-axis. Hence sines and cosines which come from ratios of legs of a right triangle to the length of the hypotenuse are also the coordinates of

MATHEMATICS CURRICULUM FOR SECONDARY COURSE RATIONALE Mathematics is an important discipline of learning at the secondary stage. It helps the learners in acquiring decision- making ability through its applications to real life both in familiar and unfamiliar situations. It predominately contributes to the development of precision‚ rational and analytical thinking‚ reasoning and scientific temper. One of the basic aims of teaching Mathematics at the Secondary stage is to inculcate the skill

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

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

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
