projection angles – complementary angles. An object thrown into the air at an angle of 75o‚ for example‚ will have the same range as if it were thrown at the same speed at an angle of 15o. An object thrown at 60o will have the same range as when the object is launched at 30o. As you can see‚ when we get the sum of 75o angle and 15o angle‚ 60o angle and 30o angle‚ in both sets we would obtain a 90o angle. This means that 75o angle and 15o angle are called complementary angles. Similarly‚ 60o angle and 30o

hundredth. 1. sin A 3. cos A SOLUTION: The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. So‚ ANSWER: SOLUTION: The sine of an angle is defined as the ratio of the opposite side to the hypotenuse. So‚ 4. tan A ANSWER: 2. tan C SOLUTION: The tangent of an angle is defined as the ratio of the opposite side to the adjacent side. So‚ ANSWER: 3. cos A SOLUTION: The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse

of two of its side lengths and the sine of the angle. ______2. Given only the three sides of a triangle‚ there is insufficient information to solve the triangle. ______3. Given two sides and the included angle‚ the first thing to do to solve the triangle is to use the Law of Sines. ______4. The Law of Sines states that the ratio of the sine of an angle in a triangle to its opposite side is equal to the ratios of the sines of the other two angles to their opposite sides. ______5.

parallel to each other. All four angles are 90 degree and the diagonal bisects the other diagonals and also the angles while the diagonals are perpendicular respectively. The adjacent sides are perpendicular. While the square is a symmetrical figure at the center‚ it divides the polygon 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
