Solution: In a right triangle, if one of the right sides is equal to half the length of the hypotenuse, this triangle is 30 60 90 and the opposite corner is 30 °. Solution: In 30 60 90 triangle, the side opposite 30 ° is half the length of the hypotenuse, and in an isosceles right triangle the hypotenuse is equal to the root of the right sides. We can solve them practically by creating a 30 60 90 triangle or a 45 45 90 triangle. Solution: There are many solutions to these questions. Since the hypotenuse is equal to the root2 of the right sides in an isosceles right triangle, we write 5root2 for the length AC. Write instead of angles and call edge 5 opposite 30 °. Solution: Let’s straighten the extension BC from corner A. Solution: If the right triangle is also isosceles, then the hypotenuse is equal to the root2 times the perpendicular sides. Solution 3: In a right triangle, the height of the hypotenuse squared is equal to the product of the lengths it separates from the corners. For the proof of this formula and to prove other formulas, see the geometry proof section. It is covered with the subject of the Euclidean theorem. Solution 2- (2): The height of the hypotenuse in a right triangle is found by dividing the product of perpendicular sides by the hypotenuse. 9.1 The Pythagorean Theorem 9.2 Special Right Triangles 9.3 Similar Right Triangles 9.4 The Tangent Ratio 9.5 The Sine and Cosine Ratios 9. If k / root5 is written instead of x, since k = 2 root5, then | BC | = 10 cm. 495) Mathematical Thinking: Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. In triangle ABC k² = x.kk root5, x = k / root5 from the Euclidean relation. Solution 2- (1): From the Pythagorean relation in ABC triangle | BC | = k.rok5.
