Which Side Lengths Form A Right Angle., Choose All That Apply, 5,12,13, 4,4,8, 2,3,4

Which side lengths form a right angle.

choose all that apply



5,12,13

4,4,8

2,3,4

 

Answer:

5,12,13

Step-by-step explanation:

5²+12²=c²

169=c²

Subtract c² from both sides.

169−c²=c²−c²

−c²+169=0

Subtract 169 from both sides.

−c²+169−169=0−169

−c²=−169

Divide both sides by -1.

c²=169

Take square root.

c=13

5²+12² = 13²

169=169

True
