Explanation:
Isosceles is 2 r the same which means that 81 and 81 minus 180
Explanation:
Isosceles is 2 r the same which means that 81 and 81 minus 180
The measure of all three angles is 81, 49.5 and 49.5 degrees.
What is Angle sum property?
According to the angle sum property of a triangle, the sum of all three interior angles of a triangle is 180 degrees. A triangle is a closed figure formed by three line segments, consisting of interior as well as exterior angles.
The angle sum property formula for any polygon is expressed as, S = (n − 2) × 180°, where 'n' represents the number of sides in the polygon. This property of a polygon states that the sum of the interior angles in a polygon can be found with the help of the number of triangles that can be formed inside it.
Given:
The triangle is isosceles which has two sides equal.
Also Two angles equals.
Let the equal angles are x.
third angle= 81 degree
Now, Using Angle Sum property
x+ +x + 81 = 180
2x= 180-81
2x= 99
x= 99/2
x= 49.5 degrees
Hence, the two smaller angles are 49.5 degrees.
