Answer:
Yes. They are Right Triangles
Step-by-step explanation:
To determine if the triangles are right triangles, all you need to do is verify whether or not the dimensions satisfy the Pythagoras Theorem.
Pythagoras Theorem:[tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]
Note that in a right triangle, the longest side is always the hypotenuse.
Given the length of the sides 1.5 feet, 2.0 feet, 2.5 feet
[tex]2.5^2=1.5^2+2.0^2\\6.25=2.25+4\\6.25=6.25[/tex]
Since the Pythagoras theorem holds, the triangles are in fact right triangles.
