Pythagoras' Theorem (or Pythagorean's Theorem) only works for this shape.
What is a right triangle?
This name is given to the set of transformations that preserve size and shape of an object.
What is an isometry or rigid motion?

What is midpoint?
Cos (x) = sin (y) when what happens?
What is x + y = 90?
The reason that cos(50) is always the same for any size triangle. Any triangle with 50 and 90 degree angles are said to be this.
What is similar to each other?
Calculate the length of the hypotenuse:
26
This transformation will change an object's orientation.
What is a reflection?
What is congruent?
You use this trig function when you have both the opposite and the hypotenuse, but need to find the reference angle.
What is sin-1( )?
You use this trig function when you have both the opposite side and the adjacent side but need the reference angle.
What is tan-1( ) ?
Calculate x (to 2 dp):
23.24
This transformation will take the pre-image to an image that is larger or smaller with proportional sides.
What is a dilation?

What is the length of bd?
12
This transformation takes (x,y) to (y, -x).

What is angle bisector?
Is the answer to tan (50) = 16/x
What is 13.43?
The angle of depression of a triangle is always equivalent to this on the adjacent congruent triangle.
What is the angle of elevation?
Abbie rides her bicycle 21 km west and then 18 km north. How far is she from her starting point? (to 2 dp)
