Question

Measure of angle A???

Answer 1

Answer:

A

Step-by-step explanation:

The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.

A property of equilateral triangles is the angles are congruent.

The sum of the 3 angles = 180°, hence the measure of each angle is

$\frac{180}{3}$ = 60° → A

Answer 2

Letter A. Which is letter 60 degrees. You can tell since it’s not a right angle, which gets rid of 90 degrees. It’s not 30 degrees because that would be too small. And it’s not 180 degrees because it’s too big.
