The quadrilateral ABCD is shown below.
Is ABCD a square?
The problem requires checking whether quadrilateral is a square.
Therefore, the quadrilateral is a square.
Yes
Yes
Look at the square below:
Is a parallelogram a square?
Both have equal sides, but a square has right angles (90°) while a rhombus can have any angles. The diagram shows right angle markers at each corner, confirming it's a square!
Look for the small square symbols at each corner! These are right angle markers that indicate 90° angles. Without these markers, you can't assume the angles are right angles.
No! A rectangle has opposite sides equal, but this shape has all four sides equal to 6. Since it also has right angles, it must be a square (which is a special type of rectangle).
Equal sides alone aren't enough! You need to check for right angle markers too. In this diagram, you can see the small squares at each vertex indicating 90° angles.
Yes! A square is a special rectangle where all sides are equal. Every square has the properties of a rectangle (opposite sides parallel, all angles 90°) plus equal sides.
Three key features: (1) All four sides equal 6 units, (2) Right angle markers at all corners, and (3) Opposite sides are parallel. These properties together define a square.
