Math Terms by: Peter and Sean

congruent 2 shapes that are the same

supplementary angle 180 together two angles that equal 180

intersecting, perpendicular. and parallel lines

adjacent angle an angle that shares a line

vertical angles the angle opposite to the other angle when two lines cross.

complementary angles 2 angles that equal to 90

Quadrilateral a shape with 4 sides

Square shape with 4 congruent sides and angles that are 90

Trapezoid a shape with 4 sides but only one set of parallel lines.

Rhombus A shape with 4 congruent sides

Rectangle 2 sets of parallel and congruent angles

Parallelogram A shape with 4 sides and the sides opposite from each other are parallel.

Parts of a Circle <--Radius ^ Diameter ^ || Radius: the distance from the center point to the edge of a circle Diameter: the distance from one edge of a circle to another going through the middle point.

Perimeter The distance around an object. To find it add up the sides Triangle Square Parallelogram w/ Rhombus Trapezoid Rectangle

Circumference the distance around a circle

Area of Triangle multiply the base times the height then divide it by 2. b x h=__, __/2=a

Area of a Rhombus or Parallelogram multiply the base times the height BxH=A

Area of a Square or Rectangle multiply the base times the height. BxH=A

Area of a Circle multiply pi (3.14) times the radius squared πr 2

Thales, Eudemus he discovered adjacent angles.

who he is He is a famous European mathmatican that had a very rich family.

he helps us today by letting us be smarter in math. helping us make more discoveries.

Real Life Square Perimeter An example would be if you had a square lawn you wanted surrounded by fence and one side was 7 feet, how would you find it?

Real Life Square Area Also if you wanted to plant 6 rows of flowers with 5 flowers in each row, how would you find it?

Real Life Circle Perimeter If you wanted to put Christmas lights around a round window, how would you find how much you need?

Real Life Circle Area Or if you are just fixing a window pane that had been broken, how would you figure how big of a pane you would need?

Angles in Everyday Objects Angles are in almost every object from corners in tables to the arches of bridges.
