A triangle has 3 angles, and also their measures include as much as 180 degrees.An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.This triangle has actually one angle of 40 deg, and two angles that measure the same; speak to the measure of each base angle x.x + x + 40 = 1802x + 40 = 1802x = 140x = 70The base angles measure 70 deg.

You are watching: The vertex angle of an isosceles triangle measures 40°. what is the measure of a base angle?


The meacertain of base angle is


More explanation:


Vertex angle of the isosceles triangle is



The triangle three sided cshed Figure.

There are three kind of triangles.

1. Equilateral triangle

2. Isosceles triangle

3. Scalene triangle

Equilateral triangle has all sides equal and all the angles are equal.

Isosceles triangle has 2 sides equal to each various other and also the 2 base angles are equal to each various other.

Scalene triangle has all sides unequal and also the angles are additionally not equal to each other.

The amount of all the angles of the triangle is


Consider the base angle as y.

The value of y can be acquired as adheres to,


The meacertain of base angle is
