Question

PLS HELP ASAP Which angle measures would make a triangle with three equal side lengths?

40°, 40°, and 1100
65°, 65°, and 65°
60°, 60°, and 60°
45°, 45°, and 90°​

Answer 1

60°, 60°, and 60°

Explanation:

A triangle with three equal side lengths is called and equilateral triangle. If the sides of an equilateral triangle are all the same, then the angles will be as well.

All triangles have a sum of 180°. This means that if you add up the the measures off all three angles, it will be 180°.

So, for equilateral triangles, you can divide the total number of degrees, (180), by the number of sides, (3).

180/3 = 60

So, each angle on an equilateral triangle has a measure of 60°

Answer 2

its the third one 60,60,60 angles in a triangle add up to 180 degrees 60+60+60=180
