Angle sum property.
Fact: the sum (i.e. addition) of all three angles in a triangle is ALWAYS exactly 180º.
Move the blue points around until two of them are 30º. What is the value of the other one?

Pythagorean Theorem
The Pythagorean Theorem is a fact about right-angled triangles. The statement of the theorem is the following.
Given a right angle triangle with sides a, b and c, where c is the hypotenuse,
.
The diagram below is a right angle triangle. Move the blue points around so that a=3 and b=4. When you have done that, what is the length of c?
Using the Pythagorean Theorem.
Find the length of c.
What is the length of c above? (Round to the nearest hundredth)
