how to work out percentage change ?

the exterior angle of a triangle is equal to what ?
The exterior angle of a triangle is equal to the sum of the interior opposite angles.
if you have two parallel lines, how do you work out the angles are the transversal liNE ?
If two parallel lines are cut by a transversal, then the alternate interior angles are equal
describe how many different angles you can find from parallel lines
4 different angles can be found
the angle at the center to the outside
twice as big
2 angle in the same segment
are =
one angle in a segment
in 90
opposite angle in a quadrilateral add up to
180
what happens to the line perpendicular from the chord
it goes through the center
tangents from a point outside the circle
are equal
what is alternate segment theorem
The angle between a tangent and a chord is equal to the angle in the alternate segmemt
what is the angle between a tangent and the radius
90
how do you work out the volume of a pyramid
1/3 * area of base * h
what would be an invariant transformation for a square
a 180 or 360 rotation
