Vertical angles: Two angles that are directly across from each other when two lines intersect.
Supplementary angles: Two angles with a sum of 180°.
Complementary angles: Two angles with a sum of 90°.
Adjacent angles: Angles that share a side.
Circumference: The distance around the outside of a circle.
Diameter: The distance from one side of a circle to the other through the center of the circle.
Radius: The distance from the center of a circle to a point on the circle.
Area: The space inside a circle.
Rectangular prism: A three-dimensional object that has six faces, two rectangular bases that are
identical and four rectangular sides.
Cross section: The two-dimensional shape that results from cutting straight across a threedimensional object.
Rectangular pyramid: A three-dimensional object where the base is a rectangle and the four
faces are triangles that meet at a point to form the top vertex.
Trapezoid: A quadrilateral with only one pair of parallel sides.

Congruent: Having the same shape and size.
Image: A new figure that is the result of a transformation.
Pre-image: The original figure prior to a transformation.
Translation: Moving a figure vertically, horizontally, or both directions without rotating or
changing the size; a slide.
Center of rotation: The point around which a figure is rotated.
Line of reflection: The line over which a pre-image is reflected to create a new image.
Reflection: A type of transformation in which one figure is a direct mirror of another.
Rotation: A transformation that turns a figure a given angle and direction around a fixed point.
Rigid transformation: Moving a shape so that it is in a new location but has the same size,
shape, and area.
Dilation: A type of transformation that changes the size but not the shape of a figure.
Scale factor: A ratio of two corresponding lengths that determines the change in size from a preimage to an image.
Similar: Having the same shape and angle measure but different sizes; expressed with the
symbol ∼.
Adjacent angles: Angles that share a vertex and exactly one side, but do not overlap.
Alternate exterior angles: The congruent pairs of angles on opposite sides of the transversal but
inside the two lines.
Alternate interior angles: The congruent pairs of angles on opposite sides of the transversal
but outside the two lines.
Corresponding angles: Congruent angles that lie in the same position relative to the intersection
of one parallel line and the transversal.
Vertical angles: Congruent angles opposite each other when two lines cross.
Angle-angle criterion (AA): If two triangles have two angles that are congruent, the triangles are
similar.
Congruent angles: Angles with the same measure.
Exterior angle theorem: The measure of an exterior angle is equal to the sum of the two remote
interior angles.
Remote interior angles: The two angles inside the triangle that do not share a vertex with the
exterior angle.
Triangle angle sum property: The sum of the measures of the angles in a triangle is 180
degrees.
