&LINES

IT IS A CHORD THAT PASSES THROUGH THE CENTER OF THE CIRCLE

WHAT IS A DIAMETER?

HE FOUND A VALUE OF PI BYSURROUNDING A CIRCLE BY POLYGONS OF INCREASING

NUMBERS OF SIDES

WHO WAS ARCHIMEDES?

HE WAS THE LIBRARIAN OFALEXANDRIA. OH, YEAH, ANDHE DID A PRETTY GOOD JOB

OF MEASURING THE CIRCUMFERENCE OF THE

EARTH

THE DIAMETER OF A CIRCLE WITHA RADIUS OF 3

WHAT IS 6?

A FIGURE HAVING 4 EQUAL SIDESAND 4 RIGHT ANGLES

WHAT IS A SQUARE?

THIS IS THE “FENCE” AROUND A POLYGON

WHAT IS THE PERIMETER?

A QUADRILATERAL WITH BOTH PAIRSOF OPPOSITE SIDES PARALLEL

WHAT IS A PARALLELOGRAM?

A = B * h

WHAT IS THE FORMULA FOR THE AREAOF A RECTANGLE OR SQUARE?

A QUADRILATERALTHAT TALKS TOO MUCH

WHAT IS SPONGE BOB SQUARE PANTS?

THE SET OF ALL POINTS IN A PLANE THAT ARE A GIVEN DISTANCE FROM

A GIVEN POINT

(THINK ABOUT THIS ONE – IT ISN’T AS HARD AS IT SOUNDS!)

WHAT IS A CIRCLE?

A TRIANGLE WITH NO EQUAL SIDES

WHAT IS A SCALENE TRIANGLE?

IT IS THE SIDE OPPOSITE THE RIGHT ANGLE IN A RIGHT TRIANGLE

WHAT IS THE HYPOTENUSE?

A TRIANGLE WITH AT LEAST TWO EQUAL SIDES

WHAT IS AN ISOSCELES TRIANGLE?

THE MEASURE OF THE THIRD ANGLE OF A TRIANGLE CONTAINING ANGLES OF

50 AND 60 DEGREES

WHAT IS 70 DEGREES?

AS THE NUMBER OF ANGLES ONA POLYGON INCREASE,

IT APPROACHES, BUT NEVER QUITE REACHES, THIS SHAPE

WHAT IS A CIRCLE?

A point where two or more rays meet, where sides of a polygon meet, or where edges of a

polyhedron meet

IT IS A SEGMENT THAT JOINS TWO POINTS ON A CIRCLE

WHAT IS A CHORD?

THESE LINES ARE IN THE SAME PLANEBUT WILL NEVER INTERSECT

WHAT ARE PARALLEL LINES?

THESE LINES INTERSECT ANDFORM EQUAL ANGLES ON ALL

FOUR SIDES OFTHE INTERSECTION

(HINT – TRY DRAWING TWO LINESTHAT MATCH THIS DESCRIPTION)

WHAT ARE PERPENDICULAR LINES?

A MYTH THAT IS STILLREPORTED REGARDING WHAT

ANCIENT PEOPLE WHOLIVED BEFORE CHRISTOPHERCOLUMBUS’ TIME BELIEVED
