Jennifer Brown Block 5Theme: Ice Cream Parlor

Point

Point: an undefined term in geometry, it names a location and has no size.

The point is at the bottom of the ice cream cone, above the 25c sign.

Line (segment)

Line(segment): a part of a line consisting of two endpoints and all points between them.

The line(segment) is the edges of the tile.

Plane

Plane: an undefined term in geometry, it is a flat surface that has no thickness and extends forever.

The plane is the floor.

Angle

Angle: a figure formed by two rays with a common endpoint.

The angle is in the metal holding the sign, next to the swirls.

Perpendicular Lines

Perpendicular Lines: lines that intersect at 90 degree angle.

The perpendicular line is where the wood meets in the corner, to the right and above the sign.

Parallel Lines:

Parallel Lines: lines in the same plane that do not intersect.

The parallel lines are the stones edges.

Square

Square: a quadrilateral with four congruent sides and four right angles.

The square is the design on the bottom part of the cone.

Trapezoid

Trapezoid: a quadrilateral with exactly one pair of parallel sides.The trapezoid is the open part of the stool between the seat and the foot rest.

Parallelogram

Parallelogram: a quadrilateral with two pairs of parallel sides.

The parallelogram is the top shapes on the cone.

Circle

Circle: the set of points in a plane that are a fixed distance from a given point called the center of the circle.

The circle is the part of the stool you sit on.

Cylinder

Cylinder: a three-dimensional figure with two parallel congruent circular bases and a curved lateral surface that connects the bases.The sprinkles are cylinders.

Sphere

Sphere: the set of points in space that are fixed distance from a given point called the center of the sphere.

The sphere is the ice cream.

Cone

Cone: a three-dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex.The ice cream cone is the cone.

Acute Angle

Acute Angle: an angle that measures greater than 0 degrees and less than 90 degrees.

The part of the metal frame furthest from the wall is an acute angle.
