Week 2-3

what is Pythagoras's formula generally known as?

• A² + B² = C²

• C² + A² = B²

• B² - C² = A²

Pythagoras is based on what kind of triangle?

do we know how to use Pythagoras?
try and answer this if A = 3 and B = 4 what is C?

• 7

• 5

• 9

• 4

what is the side called labelled C?
Hint: it begins with a H

so we have the formula for the Hypotenuse but what about if we know that?
if C = 10 and B = 6

• 8
• 4
• 15
• 12

in Pythagoras the Hypotenuse is the ?

• Middle side
• Diagonal side
• Shortest side
• Longest side

now we want to find a when we know B = 320 and C = 9000

• 8997.5

• 8994.2

• 8992.4

• 9005.8

Hard Question: find the angle if you are given two sides.
A = 12
B = 14
Q = ?

• 42.7^o

• 45.2^o

• 47.3^o

what is the term used when calculating angles in a right angle triangle?

• calculus
• algebra
• geometry
• trigonometry

Medium: Which of the following is a Pythagorean triple?

• (3, 4, 5)

• (5, 12, 14)

• (6, 8, 11)

• (7, 24, 25)
