That is just absolute value, basically what it means is take off whatever sign there was attached to it (such as a negative sign)
Ok so pythagorean theorem is
a^2+b^2=c^2
plug it in
8^2+15^2=17^2
64+225=289
289=289
yass it works so that means they do make a right triangle
yes, they make a right triangle because they're a pythagorean triple and pythagorean theorem works when you plug the numbers in.
98cm^2 - bigger triangles are 28 each, bottom one is 14. (28 x 3) + 14=98
