Answer 2

Can we conclude that a quadrilateral with one right angle is a rectangle?

No, we cannot conclude that a quadrilateral with one right angle is a rectangle. While a rectangle is a type of quadrilateral with four right angles, not all quadrilaterals with one right angle are rectangles. To determine if a quadrilateral is a rectangle, we need additional information about its sides and angles.

A rectangle is a special type of quadrilateral where all four angles are right angles. In addition to having one right angle, a rectangle also has opposite sides that are parallel and congruent. Without knowing more about the other angles and sides of the quadrilateral, we cannot definitively say whether it is a rectangle or not.

If you have additional information about the sides and angles of the quadrilateral, please provide it, and I can help you determine if it is a rectangle or not.
