From the given statements, let's determine the true and false statements.
• Statement 1:
Every parallelogram is a rhombus.
A parallelogram may have two equal sides while a rhombus must have 4 equal sides.
Therefore, this statement is False.
Not every parallelogram is a rhombus.
• Statement 2:
Every square is a parallelogram.
A parallelogram has equal opposite sides and angles while in a square the all sides and angles are equal, this means the opposite sides and angle in a square are equal.
Therefore, this statement is True.
• Statement 3:
,
• Every quadilateral is a square.
,
• A quadilateral is a polygon with four sides and edges. All four sides polygons are called quadilaterals.
,
• This means the rhombus, rectangle, trapezoid are all quailaterals.
,
• Therefore, this statement is false.
,
• Not every quadilateral is a square.
,
•
• Statement 4:
,
• Every rhombus with four right angles is a sqaure.
,
• If a rhombus have four right angles, it can be called a square because a rhombus already have 4 equal sides.
,
• Therefore, this statement is True.
