Question 1 Use the points on the circle and/or the centre to form isosceles triangles. An isosceles triangle has two sides of equal length. Since every point on circle is same distance from center We follow these steps Mark any two points in the circle Join it with the center Resulting triangle is equilateral triangle Steps of Construction 1. Mark Center as O 2. Mark any two points A and B on the circle 3. Join OA, OB and AB Thus, ∆ OAB is our required isosceles triangle
