Maren Bubeck period 6
the geometry guide for geeks
Sphere: The set of all points in a space equidistant from a given point called the center of the sphere.
Cube: A polyhedron with six congruent square faces
Rectangle: A parallelogram with four right angles
Cone: A solid that has one circular base and a vertex that is not in the same plane as the base
Circle: The set of all points in a plane that are equidistant from a given point called the center of the circle
6) Angle Bisector
Angle Bisector: A ray that divides an angle into two angels that are congruent.
7) Acute Angle
Acute Angle: An angle with the measurements between 0 degrees and 90 degrees
Line: A line has one dimension. It usually represented by a straight line with two arrowheads to indicate that the line extends without end in to directions.
9) Right Angle
Right Angle:An angle with measure equal to 90 degrees
Cylinder: A solid with congruent circular bases that lie in parallel planes
Semicircle: An arc with endpoints that are the endpoints of a diameter of a circle.
12) Vertical lines
Vertical lines: Two angles who se sides form two pairs of opposite rays
13) Vertical Lines
Vertical Lines: A line that runs up and down
14) Concentric Circles
Concentric Circles: circles that share the same center, axis or origin
Pentagon: A polygon with five sides
16) Horizontal Lines
Triangle: A polygon with three sides
Trapezoid: A quadrilateral with exactly one pair of parallel sides, called bases. The non parallel sides are legs.
19) Tangent of a Circle
Tangent of a circle: A line in the place of a circle that intersects the circle exactly one point, the point of tangency.
20) Supplementary Angles
Supplementary Angles: Two Angles whose measures have the sum 180. The sum of the measures of an angle and its supplement is 180.
Square: A parallelogram with four congruent sides and four right angles
22) Congruent Circles
Congruent circles: Two circles that have the same radius
23) Horizontal Lines
Horizontal Lines: A line that runs from left to right across the page
Octagon: A polygon with eight sides
25) Parallel Lines
Parallel Lines: Two lines that do not intersect and are coplanar
