Answer:
figure one only
Step-by-step explanation:
Hey There!
To solve this one we are going to use the Pythagorean Theorem
The Pythagorean Theorem states that the two shorter sides squared equals the longest side squared
if this is true for the triangles then they are indeed right triangles
for figure 1...
[tex]6^2=36\\8^2=64\\36+64=100\\10^2=100\\100=100[/tex]
this is true therefore figure 1 is a right triangle
for figure 2
[tex]10^2=100\\12^2=144\\144+100=244\\14^2=196\\244\neq 196[/tex]
this is not true therefore figure 2 is not a right triangle
(1) is your answer :)
