Question

match each item to the correct definition.
column a

1. the portion of a line between two points
2. equidistant
3. the point in the middle
4. a two - dimensional closed figure made up of straight line segments connected end - to - end. these segments may not cross (intersect) at any other points.
5. a polygon whose sides are all the same length and its angles have equal measure.
6. polygons that have 3 sides
7. polygons that have 4 sides
8. polygons that have 5 sides
9. polygons that have 6 sides
10. polygons that have 8 sides
11. polygons that have 10 sides
12. property of a shape that appears not to change after being reflected across a line
13. the property of a shape or object that looks identical after being rotated by a certain amount around a central point, but less than a full 360 - degree turn
14. when an object or shape can be slid or shifted a certain distance in a specific direction, without changing its appearance or orientation, and still perfectly overlap with its original position

column b
a. quadrilateral
b. pentagon
c. line segment
d. isosceles
e. midpoint
f. rotational symmetry
g. octagon
h. translation symmetry
i. polygon
j. hexagon
k. regular polygon
l. triangle
m. reflection symmetry
n. decagon

Explanation:

1. The portion of a line between two points is a line - segment.
2. Equal legs refer to isosceles (in the context of triangles).
3. The point in the middle is the mid - point.
4. A two - dimensional closed figure made up of straight line segments connected end - to - end where segments do not cross is a polygon.
5. A polygon whose sides are all the same length and angles have equal measure is a regular polygon.
6. Polygons that have 3 sides are triangles.
7. Polygons that have 4 sides are quadrilaterals.
8. Polygons that have 5 sides are pentagons.
9. Polygons that have 6 sides are hexagons.
10. Polygons that have 8 sides are octagons.
11. Polygons that have 10 sides are decagons.
12. The property of a shape that appears not to change after being reflected across a line is reflection symmetry.
13. The property of a shape or object that looks identical after being rotated by a certain amount around a central point (less than 360 degrees) is rotational symmetry.
14. When an object or shape can be slid or shifted a certain distance in a specific direction without changing its appearance or orientation and still perfectly overlap with its original position is translation symmetry.
