Naming sides of a Right Angled Triangle Intro How to Identify Hypotenuse Opposite Adjacent Identify Sides in Triangles

Trigonometry Trigonometry means “triangle” and “measurement”. Adjacent Opposite x°x°x°x° hypotenuse Each side in a RAT is given a name according to its position R ight A ngle T riangle

Hypotenuse The Hypotenuse is the longest side in a Right Angle Triangle ( RAT ). hypotenuse It is opposite the right angle

Hypotenuse The Hypotenuse is the longest side in a Right Angle Triangle ( RAT ). hypotenuse It is opposite the right angle

Opposite The Opposite side is opposite the selected angle opposite

Opposite The Opposite side is opposite the selected angle opposite

Opposite The Opposite side is opposite the selected angle opposite

Adjacent Two angles are involved. The selected A ngle and the right A ngle. adjacent The A djacent side lies between the two A ngles
