Which 3 angles can be constructed together to form a triangle? 90

60°

120°

70

20°

90, 70, 20

Step-by-step explanation:

The measure of an angle is 180 so if you add up 90,70,and 20 you get a total of 180

70, 20, 90

Step-by-step explanation:

For all triangles, the sum of the angles is 180.

I got these three angles 70, 20, 90.

To double check you can add all the angles together.

70 + 20 = 90, 90 + 90 = 180
