Classify each triangle by its angles.
1. 20°,70°,90° =
That's a right triangle because it has a 90° angle
2. 13°,27°,140° =
That's an obtuse scalene triangle because it has an
angle larger than 90°. It is scalene because none of the
angles are equal.
3. 46°,4°,86° =
That's an acute triangle because all three of its
angles are less than 90°. It is also scalene because
none of the angles are equal.
