If the vertices are on a circle, prove that it is an isosceles trapezium draw figure Y + 5y = 180 (Sum of the opposite angles of a cyclic quadrilateral is 180°)
If we draw a circle taking BC as diameter, ∠A 4x = 180° => 4x = 45° If we draw a circle taken in a AC as diameter, ∠B = 90°, Therefore the point B on the circle. What is the position of the point C based on the circle with diameter AB?ĪB2 + BC2 = 82 + 62 = 64 + 36 = 100 = AC2 What is the position of A based on the circle with BC as the diameter? Why?Ĥ. What is the position of B based on the circle with AC as the diameter? Why?ģ. In triangle ABC, AB = 8cm, BC = 6cm, AC = 10cm.Ģ.

PB = 8 cm, PC = 5 cm Circles Orukkam Questions & Answers Taking BC as diameter and drawing a circle, ∠A ( PC If circles are drawn with each side of a triangle of sides 5 centimetres, 12 centimetres and 13 centimetres, as diametres, then with respect to each circle, where would be the third vertex? ∠B = 55° (90 > 55°)ĭrawing diagonal BD and taking it as diameter of a circle.Īs both angles are greater than 90, they lie inside the circle. ∴ The top comer will be outside the circleįor each diagonal of the quadrilateral shown, check whether the other two corners are inside, on or outside the circle with that diagonal as diameterĭrawing diagonal AC and taking it as diameter of a circle As, ∠D = 90°ĭ will be on the circle. Find out whether the top corner of each triangle is inside the circle, on the circle or outside the circle.Īs 110° > 90° the top comer will be inside the circle
Suppose we draw a circle with the bottom side of the triangles in the picture as diameter.
