In a triangle ABC if r=3,R=6,r_(1)=9 then A=

Total number of parts of a triangle is 3 (b) 6 (c) 9( d)

The length of a digonal in cm of a rectangle of length 9 cm and width 6 cm is : A. 3sqrt(13) B. pm 3sqrt(13) C. 3sqrt(5) D. pm 3sqrt(5)

In triangle ABC , AB=AC and AL is perpendicular to BC at L. In triangle DEF , DE=DF and DM is perpendicular to EF at M. If (area of triangle ABC ):(area of triangle DEF )= 9:25 then (DM+AL)/(DM- AL) is equal to: त्रिभुज ABC में, AB = AC है तथा AL, BC पर L पर डाला गया लम्ब है| triangle DEF में, DE = DF है तथा DM, EF पर M पर डाला गया लम्ब है| यदि ( triangle ABC का क्षेत्रफल ): ( triangle DEF का क्षेत्रफल )= 9 : 25 है, तो (DM+AL)/(DM- AL) का मान किसके बराबर है ?

The three perpendicular distances of three sides of an equilateral triangle from a point which lies inside that triangle are 6 cm, 9 cm and 12 cm respectively. The perimeter of the triangle is :- किसी समबाहु त्रिभुज के तीनो भुजाओं से समबाहु त्रिभुज के अन्दर एक बिंदु से लंबवत दूरी क्रमशः 6 सेमी 9 सेमी और 12 सेमी है, तो त्रिभुज का परिमाप ज्ञात करें-

In the following example, can the segment joining the given points form a triangle ? If triangle is formed, state the type of the triangle considering sides of the triangle : L(6, 4), M(-5, -3), N(-6, 8)
