Pythagoras Flashcards
The triangle where all sides are the same
Equilateral
All sides of this triangle are different
Scalene
A right angle triangle has:
2 sides that join to make a right angle
What is the hypotenuse?
The hypotenuse is the longest side of a right angle triangle
How do we calculate the hypotenuse?
The length of the hypotenuse is equal to the sum of the length on the two shorter sides squared
What are surds?
Surds are NOT square numbers eg. 34
Surds don’t have exact decimal equivalents, so we use decimals to approximate their value
What is the Pythagorean triad?
The Pythagorean triad is 3 integers that satisfy Pythagoras’s Theorem
What is the formula for Pythagoras’s theorem?
c2=a2+b2
c2= the hypotenuse
Which is this largest number of the Pythagoras’s triad
c2/the hypotenuse
Show working out for proving a right angle triangle
c2=a2+b2
5^2=3^2+4^2
25=9+16
LHS=RHS
The triangle where two sides are equal
Isosceles
