Question

match each term to the correct definition
column a

1. the portion of a line between two points
2. equal legs
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. octagon
b. decagon
c. polygon
d. isosceles
e. rotational symmetry
f. regular polygon
g. line segment
h. translation symmetry
i. pentagon
j. midpoint
k. triangle
l. hexagon
m. quadrilateral
n. reflection symmetry

Explanation:

1. A line segment is the portion of a line between two points.
2. An isosceles shape has equal legs.
3. The mid - point is the point in the middle.
4. A polygon is a two - dimensional closed figure made up of straight line segments connected end - to - end.
5. A regular polygon has sides of equal length and angles of equal measure.
6. Triangles are polygons with 3 sides.
7. Quadrilaterals are polygons with 4 sides.
8. Pentagons are polygons with 5 sides.
9. Hexagons are polygons with 6 sides.
10. Octagons are polygons with 8 sides.
11. Decagons are polygons with 10 sides.
12. Reflection symmetry is the property of a shape that appears not to change after being reflected across a line.
13. Rotational symmetry is 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. Translation symmetry is 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.
