• What is a cyclic quadrilateral?

  A four-sided figure with corners on a circle
• What do opposite angles in a cyclic quadrilateral add up to?

  180 degrees
• If one angle in a cyclic quadrilateral is 130°, what is the other angle?

  50 degrees
• How does the angle at the center of a circle relate to the angle at the circumference?

  The angle at the center is double the circumference angle
• If the angle at the center is 100°, what is the angle at the circumference?

  50 degrees
• What is the relationship between angles at the circumference and the center in cyclic quadrilaterals?

  Angles at circumference are half of center angles

  They form right angles with the radius
• What is the angle between a tangent and a radius at the point of contact?

  90 degrees
• Why is angle ABC equal to 100° in the given scenario?

  Because the tangent forms a right angle with the radius
