Special Right Triangle Test-1 Solutions

Solution of Problem 1 :

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 of Problem 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 of Problem 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 of Problem 3 :

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.

Solution of Problem 4 :

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

Solution of Problem 5 :

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.
