-Point
a geometric element that has position but no extension; "a point is defined by its coordinates"
-Line (segment)
a line is a straight path that has no thickness and does not extend forever.
-Plane
a flat surface that has no thickness and extends forever.
-Angle
A figure formed by two rays with a common endpoint.
-perpendicular lines
Intersecting lines to form 90 degree angles.
-parallel lines
Lines in the same plane that don’t intersect.
-Triangle A three-sided polygon.
-Right triangle
A triangle with one right angle.
-pentagon
A five-sided polygon.
-hexagon
A six-sided polygon.
-square
A quadrilateral with four congruent sides and for right angles.
-Rectangle
A quadrilateral with four right angles.
-trapezoid
A quadrilateral with exactly one pair of parallel sides.
-parallelogram
Quadrilateral with two pairs of parallel sides.
-circle
The set of points in a plane that are a fixed distance from a given point called the center of a circle.
-cylinder
A three-dimensional figure with two parallel congruent circular bases and a curved lateral surface that connects the bases.
-sphere
The set of points in a space that are a fixed distance from a given point called the center of the sphere.
-pyramid
A polyhedron formed by a polygonal base and triangular lateral faces that meet at a common vertex.
-Acute triangle
