Solution: In an ABC isosceles triangle (| AC | = | BC |), if a point of the base [BC] is D; | AD | ² = | AB | ²- | BD |. | DC | (x² = b-m.n).

7² = 9²- | BD |. | DC | If written, | BD |. | DC | = 32 cm².

Solution 2- (1): From the Pythagorean relation in ABC triangle | BC | = k.rok5. If we say | BD | = x; | DC | = kkök5-x. In triangle ABC k² = x.kk root5, x = k / root5 from the Euclidean relation. If k / root5 is written instead of x, since k = 2 root5, then | BC | = 10 cm.

Solution 2- (2): The height of the hypotenuse in a right triangle is found by dividing the product of perpendicular sides by the hypotenuse. This is called the area relation. It is covered with the subject of the Euclidean theorem. For the proof of this formula and to prove other formulas, see the geometry proof section.

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. This is called the Euclidean theorem.

45 45 90 üçgeni soru çözümü

Solution: If the right triangle is also isosceles, then the hypotenuse is equal to the root2 times the perpendicular sides.

Solution: Let’s straighten the extension BC from corner A. Write instead of angles and call edge 5 opposite 30 °. Since the hypotenuse is equal to the root2 of the right sides in an isosceles right triangle, we write 5root2 for the length AC.

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.

30 60 90 üçgeni soru çözümü

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 °.
