`DeltaABC `में `angleA = 90 ^(@)` हो तो `BC ^(2 )` - AB ^2 कितना होगा ?

Construct a DeltaABC in which angleA = 60^(@) , angleB = 45^(@) and AB + BC + AC = 11.6 cm.

In a triangle ABC , AD is perpendicular to BC from A, if angle BAC = 90^@ , then AB^2:AC^2 is equal to : त्रिभुज ABC में, AD, A से BC पर डाला गया लम्ब है | यदि angle BAC = 90^@ है, तो AB^2:AC^2 का मान क्या होगा ?

Construct a DeltaABC in which AB = 3 cm, angleA = 90^(@) and BC - AC = 1 cm.

Construct a DeltaABC in which angleA = 30^(@) and AB = 4.5 cm and AC - BC = 1.2 cm.

In a right angled DeltaABC, angleA=90^(@) . If AC = b, BC = a, AB = c and r and R are respectively radii of incircle and circumcircle of the triangle then prove that 2(r + R) = b + c
