Parallelograms Rhombus and Squares

Samantha states that a parallelogram is always a rhombus. Is she correct?

• Yes, because a parallelogram has opposite angles that are equal in size.

• Yes, because a parallelogram has opposite sides that are equal in length.

• No, because a parallelogram does not have opposite sides that are equal.

• No, because a parallelogram does not always have 4 equal sides.

Which conclusion can be drawn?

• All quadrilaterals are kites, but all kites are not quadrilaterals.

• All parallelograms are rhombi, but all rhombi are not parallelograms.

• All squares are parallelograms, but all parallelograms are not squares.

• All parallelograms are rectangles, but all rectangles are not parallelograms.

Which figure completes this statement based on its characteristics....
polygon > quadrilateral>parallelogram> _______________

• kite

• square

• trapezoid

• traingle

Which statement is true?

• All quadrilaterals are parallelograms because they have four sides.

• All squares are parallelograms because they have 2 pairs of parallel sides.

• All trapezoids are parallelograms because they have 1 pair of parallel sides.

• All polygons are parallelograms because they have straight lines and closed sides.

A rhombus is a parallelogram.

• true

• false

• Four congruent sides

• opposite sides are parallel

• diagonals bisect one another

• opposite angles are congruent

Quadrilateral A(-4,-3), B(3,-2), C(-2,-7), D(-9,-8) is a ​ (a)   because all four sides have the same ​ (b)  

• rhombus

• length

• rectangle

• square

• perpendicular

• parallelogram

• trapezoid

• triangle

• slope

Which describes a rhombus?

• has all right angles

• has all acute angles

• has all equal sides

• has all obtuse angles

A rhombus has these characteristics:

-opposite sides are parallel

-all four sides are the same length

Based on this information, which statement must be true?

• Every square must have these same characteristics

• Every rectangle must have these same characteristics

• Every quadrilateral must have these same characteristics

• Every parallelogram must have these same characteristics

Which statement is always true for parallelograms?

• All sides have the same length

• All angles have the same measure

• Opposite sides are equal in length

• Opposite angles have different measures
