Properties of angles...
- Angles in a triangle add up to 180.
- Angles on a streight line also add to 180.
c + d = 180
Corresponding and alternate...
a = 40° (corresponding angle to angle at point D)
c = 40° (AB = CB, therefore angle a = angle c)
b = 100° (angles in a triangle add up to 180°)
e = 140° (e and c are co-interior angles)
Cube = a 3
- a is the side length
Rectangular prism = length x width x height
Cylinder = π x r 2 x h
- Direct =
y = kx
- Inverse =
y ∝ 1
x = y = k
