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

examples

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

Examples

Triangles

• 6 types of triangles

• Isosceles

• Scalene

• Equilateral

• Obtuse

• Acute

• Right

Examples

Triangle angles

• The angles of the triangle are related by all the angles added equal 180

examples

Interior/exterior angle

• The relation between interior and exterior angles are that they equal 180 together

examples

Isosceles

• An isosceles triangle has two equal sides

examples

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

Examples

Square

• Quadrilateral is a shape with 90 degree angles and the opposites are the same

Examples

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.

Examples

Examples

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

Examples

Perimeter

• To find the perimeter of the object the formula is p=2a+2b. You replace the a and bwith the formula’s on the sides of the shape. Then you do the 7 step process and solve the problem.
