let's see the definitions of the given terms:
plane = a set of infinite points and lines. it is a bidimensional entity, defined only by length and width, that extends to infinity. the correct description is  b) a flat surface that extends infinitely and has no depth; it has length and width.
perpendicular lines = two lines that intersect in only one point, forming four right angles. the correct description is  d) two lines that intersect at 90˚ angles.
parallel lines = two lines that either have no points in common or that coincide. the correct description is  a) two lines that lie within the same plane and never intersect.
circle = a closed plane curve consisting of all points that are at a given distance from a given point, called center. the correct description is  c) a set of all points in a plane that are a given distance from a point.
angle = portion of a plane included between two lines intersecting in a point. the correct description is   e) a figure consisting of two rays with a common endpoint.

The correct match are as follows:

1. plane.
b) a flat surface that extends infinitely and  has no depth; it has length and width
2. perpendicular lines.
d) two lines that intersect at 90˚ angles. 

3. parallel lines.
a) two lines that lie within the same plane and never intersect. 

4. circle.
c) a set of all points in a plane that are a given distance from a point.

5. angle
e) a figure consisting of two rays with a common endpoint.
