WebJul 18, 2024 · Note that sin(A)/a cannot give the diameter (think of the units); if one has two similar triangles ABC and A'B'C', sin(A) = sin(A'), so you would expect the radii to be *directly* proportional to the length of a side, not *inversely* proportional. Also, you can see this gives a proof of the Law of Sines, which states sin(A)/a = sin(B)/b = sin(C)/c. WebApr 5, 2024 · In a ABC,AB=AC and AD is the altitude from A to BC.

WebSelina Solutions for Class 9 Maths Chapter 10-Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides. This property is equal to two angles of the triangle being equal. Thus, we can say that an isosceles triangle has two equal sides as well as two equal angles.
