Question

On his math test, Balavan wrote that a four-sided polygon that has at least two right angles must be a rectangle or a square. Denna wrote that a four-sided polygon needs at least three right angles to be a rectangle or a square. Who is right? Explain your answer.

Answer 1

Answer:

denna is right

Step-by-step explanation:

summation of all angles in a sqare or rectangle is 360°

if 3 angles each measure 90° then summation is 270° which return 90° to be the forth angle.

Answer 2

Answer:

Sample response: Denna is correct. The sum of the angles in a quadrilateral is 360°, so if 3 of the angles are 90°, the fourth must also be 90°, creating a rectangle or a square. A quadrilateral can be drawn with the angles 90°, 90°, 120°, and 60°, but it is not a rectangle. Balavan is incorrect.
