Geometry vocabulary crossword puzzle

The point where two sides meet. (Shared end points of the line segments of a polygon.)
A polygon with 4 sides and 4 angles
A quadrilateral (4 sides & 4 angles) where opposites sides are parallel. (ie: Rectangle, square, rhombus, & diamond are parallograms)
Line segments of a polygon.
An angle that is 90 degrees (It makes a square in the corner).
A quadrilateral (4 sides & 4 angles) with one pair of parallel sides.
A triangle that has one right angle. It can also be an isosceles or scalene triangle.
A triangle that has no equal sides. All 3 sides are different lengths.
A plane figure with the same size and shape.
A plane figure that can be folded along a line so the two parts match.
The distance around the figure.
The size a surface takes up, measured in square units.
A solid shape that has: 6 square faces all equal in size, 8 vertices (corners), and 12 equal edges.
A solid shape that is perfectly round like a ball. No faces, edges, or vertices.
The flat surface of a 3D shape.
Where two surfaces join (intersect).
A flat closed shape having only 2 dimensions.
A flat figure that can be closed or not closed.
Two lines that intersect to form right angles
A triangle that has 2 equal sides.
Two rays with the same end point.
A polygon made with a continuous line which is always the same distance from the center.
A Quadrilateral with 4 sides and 4 right angles. Opposite sides are parallel.
An expression used to calculate a desired result, such as a formula to find volume or a formula to count combinations. Formulas can also be equations involving numbers and/or variables, such as Euler's formula.
The side of a right triangle opposite the right angle. Note: The hypotenuse is the longest side of a right triangle.
A point at which a graph intersects the x-axis. The x-intercepts of a function must be real numbers, unlike roots and zeros
The plane formed by the x-axis and the z-axis.
The total amount of space enclosed in a solid.
On the coordinate plane, the point (0, 0). That is, the point of intersection of the x- and y-axes. On a number line, the origin is the 0 point. In three dimensions, the origin is the point (0, 0, 0).
Any point, line, segment, ray, angle, polygon, curve, region, plane, surface, solid, etc. Formally, a geometric figure is any set of points on a plane or in space.
A line segment on the interior of a circle. A chord has both endpoints on the circle.
An angle on the interior of a plane figure.
Two distinct coplanar lines that do not intersect. Note: Parallel lines have the same slope
The longer of the two arcs between two points on a circle.
The original figure prior to a transformation. In the example below, the transformation is a rotation and a dilation.
