Respuesta :
A quadrilateral with only 2 right angles could be a trapezoid so Balavan is wrong. Denna is right because if 3 angles are right angles the the fourth angle must also be a right angle and has to be a square or rectangle.
Denna is right a four-sided polygon need at least three right angles to be a rectangle or a square.
Given that
On his math test, Balaban 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.
We have to determine
Who is right?
According to the question
The sum of the angles in a quadrilateral is 360°, and a rectangle or square has four 90° angles.
A quadrilateral can be formed with two right angles and two angles that are other measures.
If the three angles are 90°, the total is 270°, so the fourth angle is 90°.
A quadrilateral that has two right angles could be a trapezoid.
Denna is right because if 3 angles are right angles the fourth angle must also be a right angle and has to be a square or rectangle.
Hence, Denna is right a four-sided polygon need at least three right angles to be a rectangle or a square.
