Special Right Triangle Test-4 Solutions

Solution of Problem 1 :

Since the three sides of the triangles in an equilateral triangle are equal ( sss ), the triangles are equal. Accordingly, it is 2x = 60 °, x = 30 °.

Solution of Problem 4 :

| EC | = 17-6 = 11 cm, if the angles are written instead, the length x length is 7 cm from the analogy of the two triangles aaa .

Solution of Problem 5 :

m (EBA) = 45 °, | BC | = | AD | and | BC | = | AB | is | AD | = | AB | Since m (ADB) = 45 °. Since the right sides of the US right triangle are 4 cm, the hypotenuse (| BD |) is 4 root2 cm.

Solution of Problem 6 :

In equilateral triangle ABC, the height is median. So | BN | = | NC | is. | BD | = 3 | CD | is | BN | = | NC | = | CD | happens. In the right triangle, x = 6 cm from the Pythagorean equation.

Solution of Problem 7 :

Since the two triangles are equal ( sas ), m (BCE) = 60 °. Let’s write the cosine theorem, since two sides and one angle of the triangle are known. x² = 7² + 8²-2.7.8.cos120 hence the value of x is 13 cm.

eşkenar üçgen çözümlü sorular 9 sınıf

Solution of Problem 8 :

In triangle ABC | AF | = | FB | Since the height we will draw from point C to the edge of AB is perpendicular at point F. In an equilateral triangle, the heights are equal. Therefore | BE | = | CF | Then | CF | = | CD | happens. Since the base angles in an isosceles triangle with a peak angle of 150 degrees will be 15 °, the measure of the alpha angle is 90 ° -15 ° = 75 °.
