100
this is an exact location in space
point
100
This one has three congruent sides, and this one has three "cute" angles.
equilateral and acute triangle
100
This angle is exactly 90 degrees
right angle
100
You use this formula to find the P of a rectangle p= 21+ 2w p=(2 x 60) + (2 x 40) p= 120+80 p= 200
Perimeter
100
This is the value of pi.
3.14
200
This is a straight path between two points
line segment
200
this one rymes with "fuse", this one has two congruent sides.
obtuse and isosceles
200
This one is exactly 180 degrees.
straight angle
200
The formula A = lw means this of a rectangle equals the length times the width.
area
200
This is a straight line from the center of the circle to the circumference.
radius
300
this is an endless straight path starting at one point
ray
300
Finally, a triangle that is right on target! A very "scaley" fellow is this one.
right and scalene triangle
300
This one is less than 90 degrees.
acute angle
300
volume also means this
number of cubic units
300
Example: c=3.14d c= 3.14 x 12 c= 37.68 A formula for a circle
circumference
400
Lines that cross at one point. And lines that intersect to form four 90 degree angles are these two types of lines.
intersecting and perpendicular lines
400
Example: P=58+75+48 P=181 This is the formula for this type of triangle
perimeter
400
This angle is greater than 90 degrees.
obtuse angle
400
Example: v=lwh v=10x15x4 v=600
volume of a rectangular prism
400
Example: v = 3.14 x r to the second times h v = 3.14 (1.4 x 1.4) x 20 v= 123.088
formula for volume of a cylinder
500
Lines that never intersect and are always the same distance apart.
parallel lines
500
Example:A= 1/2bh Example: 12=1/2 x 4x/2 A=1/2 x12x15 12= 4x/2 A=12x15/2 = 180/2 =90 12/2 = 2x/2 x=6
Formula for the Area of a Triangle, base of a triangle
500
An angle is formed by two rays or line segments with a common endpoint.
vertex
500
Example:A=lw A=12x8 A=96
Formula for the area of a rectangle
500
Example: A = 3.14 times r to the second A = 3.14 (7 x7) A= 3.14 x 49 = 153.86
