Two-Dimensional Shapes

Which statement is true?

• All parallelograms have 2 sets of congruent sides, rhombuses are parallelograms, so all rhombuses have 2 sets of congruent sides.

• All parallelograms have 2 sets of congruent angles and rectangles have 4 congruent angles so all parallelograms have 4 congruent angles.

• All parallelograms have 2 sets of parallel sides and parallelograms are quadrilaterals so all quadrilaterals have 2 sets of parallel sides.

Which shapes always have 4 congruent sides?

• square

• rhombus

• quadrilateral

• rectangle

Which shapes sometimes have 4 congruent sides?

• square

• 4 sides and 4 vertices

Which shapes always have 4 right angles?

• square

• rectangle

• parallelogram

• quadrilateral

• rhombus

Which statement is correct?

• All squares are rectangles. Rectangles have 4 right angles. Therefore all squares have 4 right angles.

• All squares are rectangles. Rectangles have 4 right angles. Therefore all squares have 4 right angles.

• Only some squares are rectangles. Rectangles have 4 right angles. Therefore only some squares have 4 right angles.

Choose the correct statement.

• A rectangle is always a kite, because it has 4 right angles.

• A square is always a rhombus because i has 4 equal sides.

• A square is always a rectangle because it has 4 right angles.

• A square is a trapezoid, because it has 4 equal sides.

True or False: A four sided figure with four equal sides is always a quadrilateral and a rhombus but not always a rectangle.

• True

• False
