Step-by-step explanation:

A parallelogram is basically a shape with 4 corner and/or sides that has 2 sides that are 'parallel', as stated in the name itself.

D.) Square MARK ME BRAINLIEST!!

Step-by-step explanation:

A quadrilateral is a rectangle if and only if it has four right (congruent) angles. ABCD is a rectangle if and only if ∠A≅∠B≅∠C≅∠D.A quadrilateral is a rhombus if and only if it has four congruent sides. ABCD is a rhombus if and only if AB⎯⎯⎯⎯⎯⎯⎯≅BC⎯⎯⎯⎯⎯⎯⎯⎯≅CD⎯⎯⎯⎯⎯⎯⎯⎯≅AD⎯⎯⎯⎯⎯⎯⎯⎯.A quadrilateral is a square if and only if it has four right angles and four congruent sides. By definition, a square is a rectangle and a rhombus. ABCD is a square if and only if ∠A≅∠B≅∠C≅∠D and AB⎯⎯⎯⎯⎯⎯⎯≅BC⎯⎯⎯⎯⎯⎯⎯⎯≅CD⎯⎯⎯⎯⎯⎯⎯⎯≅AD⎯⎯⎯⎯⎯⎯⎯⎯.You can always show that a parallelogram is a rectangle, rhombus, or square by using the definitions of these shapes. There are some additional ways to prove parallelograms are rectangles and rhombuses, shown below:1.  A parallelogram is a rectangle if the diagonals are congruent. ABCD is parallelogram. If AC⎯⎯⎯⎯⎯⎯⎯⎯≅BD⎯⎯⎯⎯⎯⎯⎯⎯, then ABCD is also a rectangle.2.  A parallelogram is a rhombus if the diagonals are perpendicular. ABCD is a parallelogram. If AC⎯⎯⎯⎯⎯⎯⎯⎯⊥BD⎯⎯⎯⎯⎯⎯⎯⎯, then ABCD is also a rhombus.3.  A parallelogram is a rhombus if the diagonals bisect each angle. ABCD is a parallelogram. If AC⎯⎯⎯⎯⎯⎯⎯⎯ bisects ∠BAD and ∠BCD and BD⎯⎯⎯⎯⎯⎯⎯⎯ bisects ∠ABC and ∠ADC, then ABCD is also a rhombus.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
