Geometry project

1. a type of symmetry in which a figure looks exactly the same after rotating it some angle less than 360
4. every polygon has a exterior angle sum of 90 degrees
6. to calculate the measure of one interior angle of a regular polygon
11. the sum of the measure is 360 degrees
13. the specific point around the shape is rotated to achieve rotational symmetry
14. a quadrilateral with four right angles
15. two parallel sides
17. a quadrilateral with four congruent sides that are equal in length
18. two shapes or figures that are the same exact size and shape
20. a polygon having n sides and n verticals

2. a quadrilateral with only one pair of parallel sides and non congruent base angles
3. a quadrilateral with two sets of parallel lines
5. an imaginary line that divides a shape into two identical halves
7. a polygon where all the sides are equal in length
8. trapezoid a quadrilateral with one set of parallel lines with congruent base angles
9. a quadrilateral with two pairs of congruent sides
10. when an object appears the same after being rotated by 360/n degrees
12. polygon that has all equal sides and angles
16. a quadrilateral with four equal sides and four right angles
19. a polygon where all the angles are equal in length
