Question

Use the Pythagorean Theorem to determine if a triangle with side lengths 4ft., 10ft., and 12ft. is a right triangle.

Answer 1

Answer:

a=4ft; b=10ft; c=12ft

By pythagoras,

a^2+b^2=c^2

a^2+b^2=4^2+10^2=16+100=116

c^2=12^2=144

=>a^2+b^2 =/= c^2

i.e a^2+b^2 is not equal to c^2

=>it is not a right triangle

Answer 2

Answer:

Step-by-step explanation:

In right angle triangle a.c.p.therom

Hypotenus^square = oppsite^square + adjacent side^square

12^2 = 10^2 + 4^2

144 = 116

144 does not equal to 116

So it is not a right angle triangle
