Answer:
All statements are true.
Step-by-step explanation:
In a square, we have
all sides equal
all angles equal to 90 degrees
diagonals always bisect each other and at right angles.
Only square is the quadrilateral which satisfies all the above properties.
A parallelogram has diagonals which do not cut at right angles.
A rhombus has all sides equal but not all angles. Neither diagonals are equal in a rhombus.
Given statement is False, if a light cost $3, it could be either Green or Yellow.
Converse: If the light bulb was Yellow, then the cost was $3 = True
Contrapositive makes both statements negative and switches the order of the original statement.
So something like: If the light bulb is not yellow, then the cost would not be $3 = False because two colors cost the $3.
Inverse makes both statements negative but keeps the same order.
Something like : If the light bulb did not cost$3 then the light bulb was not yellow = False because two colors cost the $3.
