A perpendicular bisector of a segment AB is actually the set of all points that are equidistant from A and B. You can see this by picking an arbitrary point C on the line, and the intersection ...
WebA circle having a radius of 9 cm circumscribes a right triangle whose area is 43.23 sq. cm. If one of the sides is 18 cm long, find the other sides. Solution: The area of a triangle, At = 1 2bh A t = 1 2 b h. At = 43.23= 1 2bh A t = 43.23 = 1 2 b h. b = 86.46 h b = 86.46 h. By Phytagorean Theorem: 182 = b2 +h2 18 2 = b 2 + h 2.
