Geometry Shapes

Rectangle

A Quadrilateral with 4 sides and 4 right angles. Opposite sides are parallel.

point

A location on a plane; it has no length, width, or depth. . B

Symmetry

A plane figure that can be folded along a line so the two parts match.

Triangle

A polygon with 3 sides and 3 angles.

Quadrilateral

A polygon with 4 sides and 4 angles.

Parallelogram

A quadrilateral (4 sides & 4 angles) whose opposites sides are parallel. (rectangle, square, rhombus, are parallelograms)

Trapezoid

A quadrilateral (4 sides & 4 angles) with exactly one pair of parallel sides.

Square

A quadrilateral with 4 equal sides and 4 right angles. Opposite sides are parallel.

Rectangular Prism

A solid shape that has: 6 faces (4 rectangles & 2 squares), 8 vertices (corners), and 12 equal edges.

Cube

A solid shape that has: 6 square faces all equal in size, 8 vertices (corners), and 12 equal edges.

Sphere

A solid shape that is perfectly round like a ball. No faces, edges, or vertices.

Cone

A solid shape with a circular base and a curved surface that come to a point (vertex).

Pyramid

A solid shape with a quadrilateral as a base and triangular faces that come to a point (vertex or apex)

Cylinder

A solid shape with one curved surface and two congruent circular bases.

Isosceles Triangle

A triangle that has 2 equal sides.

Equilateral triangle

A triangle that has 3 equal sides.

Scalene Triangle

A triangle that has no equal sides. All 3 sides are different lengths.

Right Triangle

A triangle that has one right angle.

Right Angle

An angle that measures 90 degrees .

Ray

Part of a line that starts at an end point and goes in one direction without end.

Line Segment

Part of a line with two end points that can be measured.

Volume

The amount of space occupied by a 3D object, measured in cubic units.

Perimeter

The distance around the figure.

Face

The flat surface of a 3D shape.

Line of Symmetry

The line that divides two matching parts. It can be vertical, horizontal, or diagonal.

Area

The size a surface takes up, measured in square units or length times width.

Angle

Two rays with the same end point (vertex).

Edge

Where two surfaces join.

Rhombus

a parallelogram with four equal sides and equal opposite angles.
