To get from point A to point B you must avoid walking through a pond.  To avoid the pond, you must walk 34 meters south and 41 meters east.  To the nearest meter, how many meters would be saved if it were possible to walk through the pond?

• 35

• 22

• 58

• 75

Side b in the triangle is the hypotenuse

• True

• False

Which side is the hypotenuse?

• AB

• AC

• BC

• Not enough information to determine

Which side is the hypotenuse?

• DF

• DE

• EF

• Not enough information to determine

Answer explanation

The information is not given to you that the angle at D is 90 degrees. Therefore we don't know that it is a right-angled triangle and therefore this triangle does not have a hypotenuse.
