Question

The ratio of angle measures 1:2:2. classify the triangle by its angle measures

Answer 1

Short Answer; it pretty much has to be Isosceles.

Let the smallest angle (represented by 1) be x

Then the other two angles are 2x and 2x

Every triangle has 180o and 3 angles.

x + 2x + 2x = 180

5x = 180 Divide by 5

x = 180/5

x = 36

Therefore the angles are

36

72

72

Two angles are the same. The triangle is Isosceles.
