WebAug 1, 2024 · A triangle A B C is given with B C = a, A C = b and A B = a 2 + a b. The perpendicular bisector of A C intersects A B at P. Find the perimeter of A P C. Any point on the perpendicular bisector is equidistant from both the ends of the segment that they bisect. This means that A P = P C, or A P C - isosceles. WebTick the correct answer and justify: In ΔABC, AB = 6 3 cm, AC = 12 cm and BC = 6 cm. The angle B is: Options 120° 60° 90° 45° Advertisement Remove all ads Solution Given that, AB = 6 3 cm, AC = 12 cm, and BC = 6 cm It can be observed that AB 2 = 108 AC 2 = 144 And, BC 2 = 36 AB 2 +BC 2 = AC 2

WebThe angles A,B and C of a triangle ABC are in A.P. If b:c=√3:√2, then the angle A is Q. The angles A, B and C of a triangle ABC are in AP, if b : c = : √3:√2, then the angle A is Q. In any ΔABC, if a2,b2,c2 are in arithmetic progression, then prove that cotA,cotB,cotC are in arithmetic progression. Transformations MATHEMATICS Watch in App WebIn a A B C, a 2 + b 2 + c 2 = a c + a b 3 ,then the triangle is ( A) equilateral ( B) isosceles ( C) right angled ( D) none of these The given condition is a 2 + b 2 + c 2 = a c + a b 3. Using sine rule, a = 2 R sin A, b = 2 R sin B, c = 2 R sin C ,we get sin 2 A + sin 2 B + sin 2 C = sin A sin C + sin A sin B 3 I am stuck here. trigonometry chips away cheltenham
