Show that if a quadrilateral has one angle measuring 90°, and two opposite angles sum to 180°, is it cyclic? Prove your answer.
💡 Hint: Look back on theorem implications.
Given a cyclic quadrilateral with angles A, B, C, and D where \( \angle A + \angle C = 180° \) and \( \angle B + \angle D = 180° \), design a geometric figure showing these properties.
💡 Hint: Use known angles to guide your figure.
