This document discusses various geometry concepts including:
1) Types of angles such as supplementary, complementary, vertical, corresponding, alternate interior, and alternate exterior angles.
2) Types of triangles such as isosceles, scalene, equilateral, obtuse, acute, and right triangles.
3) Properties of polygons including their classification based on number of sides, interior/exterior angles, and finding the sum of interior angles.
4) Specific polygons such as squares, rectangles, rhombi, parallelograms, and kites.
5) Calculating perimeter using side length formulas.
2. Angles P.1
Supplementary angles are two angles that add
up to 180
Complementary angles are two angles that
add up two 90
Vertical angles are two angles that are
opposite to each other when cut by a
transversel
4. Angles P.2
Corresponding angles are two angles that are
at the same position of the transversal
Alt. interior angles are angles that are on
opposite sides but inside the two lines
Alt. exterior are angles that are on opposite
sides but outside the two lines
Same-side interior angles are angles that are
inside the two lines on the same side of the
transversal
14. polygons
A polygon is a shape with straight sides and
the shape is closed. They are classified by how
many sides it has
Convex polygon is a shape that points all the
angles out
Regular polygons are polygons where all
angles equal the same
18. Polygons diverse
Parallelograms are parallel to each side and
opposites are the same
Rectangles sides are all equal and have same
characteristics as parallelogram
Rhombus is same as rectangle but has same
opposite angles
Square has all the rules of the shapes
Kite has equal angles on opposite sides.
21. Sum of int. angles on polygons
To find this you take an axis and you draw
lines to each angle you can, then you find out
how many triangles it makes and multiply that
by 180
23. Perimeter
To find the perimeter of the object the
formula is p=2a+2b. You replace the a and b
with the formulas on the sides of the shape.
Then you do the 7 step process and solve the
problem.
