Exploring Diagonals in Quadrilaterals

What defines a rectangle?

• Four right angles and opposite sides are equal

• One pair of parallel sides

• Four equal sides

• Two pairs of adjacent sides of the same length

What is unique about a trapezoid?

• It has two pairs of equal adjacent sides

• All sides are equal

• It has only one pair of parallel sides

• It has four right angles

Which quadrilateral has exactly one pair of parallel sides?

• Parallelogram

• Trapezoid

• Square

• Rectangle

What does 'adjacent' mean in the context of quadrilaterals?

• Sides that are opposite each other

• Sides that have a right angle

• Sides that are touching each other

• Sides that are parallel to each other

What is the difference between adjacent and opposite sides in a quadrilateral?

• Opposite sides never touch

• Adjacent sides touch each other

• Opposite sides are always parallel

• Adjacent sides are longer

What is a diagonal in a quadrilateral?

• A line segment perpendicular to one of the sides

• A line segment parallel to one of the sides

• A line segment connecting adjacent vertices

• A line segment connecting non-adjacent vertices

How many triangles are formed when a diagonal is drawn in a quadrilateral?

• One

• Two

• Three

• Four

What type of triangle is formed by drawing a diagonal in a rectangle?

How can triangles be named using their vertices?

• In the order the vertices appear on the shape

• In the order of their size

• Following the alphabetical order

• In any random order

Can a diagonal in a rhombus create a right triangle?

• Sometimes

• Only if the rhombus is also a square

• Never

• Always
