Adjacent angles
Two angles are Adjacent when they have a common side and a common vertex (corner point), and don't overlap.
Alternate exterior angles
Alternate exterior angles are congruent. Alternate exterior angles are defined as two exterior angles, which cut through a set of parallel lines.
Alternate interior angles
these are inside the two parallel lines, and are on opposite sides of the transversal.
And they are equal in measure.

Complementary angles
Complementary angles are two angles that sum up to 90°.
Corresponding angles
the angles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
Supplementary angles
Supplementary angles are angles that have angles that add up to 180°
vertical angles
Vertical angles are each of the pairs of opposite angles made by two intersecting lines.

Supplementary angles
Parallel lines
Parallel lines are a set of lines that run straight side by side and never ending.
Perpendicular Lines
at an angle of 90° to a given line, plane, or surface. Shows with a small square at the corner of the 90° angle.
Transversal line
a transversal is a line that passes through two lines in the same plane at two distinct points.
perimeter
The outside line or boundary for a geometric figure.
area
In geometry the area of a shape is the size of the surface.
surface area
The total area of the surface of a three-dimensional object.
volume
Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid in cubic meters.
circumference
Circumference = π × diameter = 2 × π × radius.
diameter
the diameter of a circle is any straight line segment that passes through the center of the circle.
radius
The distance from the center to the edge of a circle. It is half of the circle's diameter.
face
a face is a flat surface that forms part of the boundary of a solid object
edge
an edge is a particular type of line segment joining two vertices in a shape.
vertex
a vertex is a special kind of point that describes the corners or intersections of geometric shapes.
