Find the area of a right angled triangle whose radius is 5 cm in length with the radius 5 cm at the hypotenuse from the vertex, so the area of the right angle is ? answer in Hindi |

Answer» Step-by-step explanation: ASSUME a right TRIANGLE ABC, right ANGLED at B. So, AC is HYPOTENUSE & Altitude drawn from B to AC is BD= 4 cm Circumcentre of any right triangle is the mid point of its hypotenuse. Let M be the mid point of hypotenuse AC. So, M is the circumcenter & AM = CM = circumradius = 5 cm. Mow, area tri (ABC) = 1/2* AC * BD => area tri ABC) = 1/2*10* 4 => areatri ABC) = 20 cm? Area Right triangle ABC) = 20 cm |
