Properties of Right Triangle

d

Relation between sides

A Greek mathematician Pythagoras identified that the direct relation between sides of a right triangle. He proved that the square of length of hypotenuse is equal to sum of the squares of lengths of opposite and adjacent sides of that right triangle. Therefore, it is called Pythagorean Theorem.

1. Length of Opposite side is $a$
2. Length of Adjacent side is $b$
3. Length of Hypotenuse is $c$

Then, the Pythagorean Theorem is written as the following algebraic equation.

$\large c^2 = a^2 + b^2$

Angle equals to $0^°$

d

1. Length of Opposite side (Perpendicular) = 0
2. Length of Adjacent side (Base) = Length of Hypotenuse

Angle equals to $30^°$

Angle equals to $45^°$

Angle equals to $60^°$

Angle equals to $90^°$
