Question

identify each of the following triangles as acute, obtuse, right, or equiangular. (there may be more than one term that applies to these triangles )
a. choose the correct classification below.
a. acute
b. right
c. acute and equiangular
d. obtuse

Explanation:

Step1: Recall triangle - type definitions

An acute triangle has all angles less than 90°. A right - triangle has one angle equal to 90°. An obtuse triangle has one angle greater than 90°. An equiangular triangle has all angles equal (each 60°).

Step2: Analyze triangle a

Since all angles of triangle a appear to be less than 90°, it is an acute triangle. Also, since all angles seem to be equal, it is equiangular.

Answer:

C. acute and equiangular
