Leia made a triangle that had one 90 degree angle and two acute angles. Which term describes Leia's triangle?

• Right triangle, because there is one 90 degree angle.

• Acute triangle, because there are two acute angles.

• Obtuse triangle, because the largest angles is obtuse.

• Right triangle, because all three angles are 90 degrees.

• Point K

• Point M

• Point N
