The hypothenuse of a triangle is the side opposite the right angle.

Read the hypothenuse of each of the triangles 5, 6, and 11.

Either side about the right angle may be considered the base.

Then the other side will be the perpendicular.

In the triangle 3, if i j is the base, which side is the perpendicular?

If g i be considered the base, which side is the perpendicular?

In triangle 5, if n o is the base, which side is the perpendicular?
