Right Angles in Quadrilaterals: Can a Quadrilateral Have Four Right Angles? #3305101 (License: Personal Use)

The image displays a labeled rectangle ABCD, with square symbols at each vertex indicating right angles (90°). To the right, a semicircular protractor visually reinforces the measurement of a right angle at 90°, emphasizing geometric accuracy. This visual pairing helps learners connect abstract angle concepts with real-world tools and shapes.

Used in educational math content for middle or high school geometry lessons, especially when teaching properties of quadrilaterals, angle sums, and classification of polygons. Matches user intent seeking visual confirmation of theoretical concepts.
