Geometric Lines and Shapes

The area of a proportion of a circle defined by the central angle

An angle measuring exactly 180°

Polygon for which all interior angles are less than 180°; vertices seem to point outward; all diagonals will be contained within the polygon

And angle measuring between zero and 90°

If a transversal intersects two parallel lines then the alternate interior angles are congruent

Triangle with each angle being an acute angle; each angle measuring less than 90°

And angle measuring exactly 90°. All right angles are congruent

The figure formed by the intersection of two rays, lines, or line segments, or else by two raise with a common endpoint

The pair of opposite angles created when two lines intersect. the angles are congruent

If two angles of one triangles are congruent to angles of another triangle, The triangles are similar

A multi sided, closed figure made up of vertices and edges

A polygon with sides and angle measures that are not all the same

Triangle with one obtuse angle; one angle measuring more than 90°

A point where to rays, lines, or line segments meet, such as the point where to rays, lines, or line segments intersect to form an angle

On a polygon, a line segment drawn from one vertices to another that is not a side

If the three sets of corresponding sides of two triangles are in proportion the triangles are similar

An angle made from points on a circle circumference

A circle drawn on the inside of the polygon that touches the midpoint of each side

The sum of all of the areas of all faces of a solid object

The length of a segment that goes from one point on a circle through its center, and continues on to the another point on the other side of the circle

Lying on the same line

Polygon with four vertices and four sides (parallelogram)

And angle measuring between 180° and 360°

Triangle with at least two sides are congruent to each other and their two base angles congruent to each other
