Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) that has at least one pair of parallel sides.

Front

Does a trapezoid have rotational symmetry?

Back

No, a trapezoid does not have rotational symmetry.

Front

What is reflection symmetry?

Back

Reflection symmetry, or line symmetry, occurs when one half of an object is a mirror image of the other half.

Front

Does an equilateral triangle have reflection symmetry?

Back

Yes, an equilateral triangle has reflection symmetry.

Front

What is rotational symmetry?

Back

Rotational symmetry is when an object can be rotated around a central point and still look the same at certain angles.

Front

Does a square have rotational symmetry at 90 degrees?

Back

Yes, a square has rotational symmetry at 90 degrees.

Front

What is the difference between intersection and union in set theory?

Back

Intersection refers to elements common to both sets, while union refers to all elements from both sets.

Front

What does the term 'intersection' mean in geometry?

Back

In geometry, intersection refers to the point or set of points where two or more figures meet.

Front

What does the term 'union' mean in geometry?

Back

In geometry, union refers to the combination of all points from two or more figures.

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments.
