What you are hoping for is that it is a right triangle. Use Pythagoras formula.
<span><span>c2</span>=<span>a2</span>+<span>b2</span></span>
where c is the longest side. IF you get a true statement out of this then your triangle is a right triangle.
<span><span>162</span>=<span>102</span>+<span>112</span></span>?
<span>256=100+121</span>?
<span>256=221</span><span>?
no, 256 does not equal 221, so in this case it is not a right triangle </span>.and it is scalene triangle with three different sides
If it's Jose, Brad, and Ed it's an acute triangle, it has no 90 degree angle, if it's Jose, James, and Malcolm it is a right triangle because the line to Jose and Malcolm is straight I think not sure how to explain
