GEOMETRY



I will teach you many things about Geometry BUT if u don't Understand it i'm gonna say
i will come and get u
what is the meaning of geometry
there are two meaning of geometry and they are:
1.a part of mathematics concerned with questions of size, shape, and relative position of figures and with properties of space.
2.all about sphape shape shapes
AREA OF THE SHAPES
AREA OF RECTANGLE
formula
L-length or base of the rectangle
W-width or height of a rectangle
L x W= A
AREA OF A TRIANGLE
formula
triangle is a half of rectangles
B x H
2
AREA OF CIRCLES
D-diameter
R- radius
Ï€ -3.14
Ï€ x r x r
AREA OF SQUARE
same as the rectangle
L- Lenght or base
W-width or height
L x W= A
perimeter
To find the perimeter of a rectangle, triangle and square you add the measurments of all the sides.
RIGHT TRIANGLE
A- Altitude----------------make the
B-base of a triangle-----right angle
c hypotenuse- longest side
Finding C
the hypotenuse is missing
c2=a2=b2 or a2 + b2 = C2
Finding B
the base is missing.
c2= a2+ b2 or b2= c2 - a2
Finding A
the altitude is missing.
c2= a2+ b2 or a2= c2+ b2
CUBE
formula area of the base x height
LxWxH
RETANGULAR PRISM
formula of the base x height
(LxW) xH
TRIANGULAR PRISM
area of the base xheight
(bxh) H
2
CYLANDER
area of the base x height
(Ï€r2)
