Geometry project

3. a triangle having two sides of equal length
5. When an object is turned clockwise or counterclockwise around a given point
7. a straight line segment that passes through the center of a circle or sphere from one side to the next
9. an angle whose apex is the center O of the circle and whose legs are radii intersecting the circle in two points A and B
11. having the same size and shape
12. the distance from the center of the circle to any point on its circumference
14. two angles whose measure add up to 90 degrees
15. The longer arc connecting two endpoints on a circle

1. two lines in the same plane that are at equal distance from each other and never meet
2. the distance from the center of the circle to any point on its circumference
4. a air of angles formed when the transversal line crosses two lines .
6. two angles are adjacent if they have a common side and common vertex
8. the angle formed in the interior of a circle when two chords intersect on the circle
10. the pair of angles formed on the inner side of parallel lines but on the opposite sides of the transversal
13. a transformation that changes the size of a geometric figure but dos not change its shape
