Question

a triangle has angle measurements of 88°, 59°, and 33°. what kind of triangle is it?
equilateral
isosceles but not equilateral
scalene

Explanation:

• An equilateral triangle has all angles equal to \(60^{\circ}\). Since \(88^{\circ}

eq59^{\circ}
eq33^{\circ}
eq60^{\circ}\), it is not equilateral.

• An isosceles triangle has at least two equal angles. Here, \(88^{\circ}\), \(59^{\circ}\), and \(33^{\circ}\) are all different.
• A scalene triangle has all angles (and all sides) different. Since \(88^{\circ}

eq59^{\circ}
eq33^{\circ}\), it meets the definition of a scalene triangle.

Answer:

scalene
