Unit 5:Geometry

2. the measure of an angle that subtends an arc with a length of exactly one radius
4. a 3D figure built with a base of a polygon and triangular faces all connected together.
6. a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.
7. a line that splits an angle into two equal angles
8. a line segment in a triangle that joins a vertex to the midpoint of the opposite side
9. a 3D geometrical shape, that has all its surface points equidistant from a common point.
12. divides a line segment into two equal pieces and intersects the bisected line segment at a right angle
16. a line segment extending from the center of a circle or sphere to the circumference or bounding surface.
18. the space occupied within the boundaries of an object in three-dimensional space
20. a part of line that has endpoints on both sides to represent a distinct start and end
21. an angle with a vertex on the circumference of a circle and legs that contain chords of a circle
22. a line segment in a triangle through the vertex perpendicular to a line containing the side opposite of the vertex
23. same shape, corresponding angles are congruent
24. The total area of the surface of a three-dimensional object.

1. a straight line that passes through the center of a circle and divides the circle into two sections/semicircles
3. same shape and size
4. a solid shape with two identical and parallel faces
5. a line that connects two vertices of a polygon or solid, whose vertices are not on the same edge
6. A solid 3D object that has a circular base joined to a point by a curved side.
10. lines the same distance apart that never intersect
11. the mass of an object divided by its volume.
13. a closed, two-dimensional curved shape
14. the circular movement of an object around a centre
15. a smoot curve on a circle that joins two endpoints
17. the shape formed when cutting an object parallel to its base with a plane
19. a 2D shape whose sides are parallel to each other
