This document defines and describes several geometric shapes including linear pairs of angles, octagons, parallel lines, parallelograms, arcs, circles, trapezoids, and isosceles triangles. It provides brief definitions for each shape stating their key properties such as number of sides, angles, and relationships between sides or angles.

1. The Shapes Are All Around
By: Savanah Gales

2. Linear Pair
A linear pair of angles is
formed when two lines
intersect. Two angles are
linear if they are adjacent
angles formed by two
intersecting lines and they
are supplementary.

3. Octagon
A polygon with 8 sides
and 8 angles.

4. Parallel lines
Two lines on a plane
that never meet and
are always the same
distance apart.

5. Parallelogram
A parallelogram
is a
quadrilateral
with opposite
sides that are
parallel. The
opposite angles
are congruent.

6. Arc
An Arc is a curved line
that is part of a circle.

7. Circle
A circle is a shape with all
points the same distance
from its center. A circle is
named by its center.

8. Trapezoid(Quadrilateral)
A quadrilateral with
only one pair of
parallel sides.

9. Isosceles
A triangle with
two congruent
sides.
