44 degrees
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees

The 3 angles of a triangle always add up to 180 degrees. You have 110 and 43, so that is 153 degrees. Subtract 153 from 180, and that is the remaining angle.
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.

It is an isosceles triangle
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
For an isosceles triangle with vertex 46 degrees, the sum of the remaining two base angles is 180-46 = 134 degrees. Base angles are equal because it's isosceles, so each angle is half of their sum. 134/2 = 67 degrees. Thus, any isosceles trapezoid formed inside that isosceles triangle by drawing parallel lines to the triangle's base, will have base angle measures of 67 degrees, which are triangle's base angles.
The three interior angles measure 45, 45 and 90 degrees.

The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
That's an isosceles triangle.
A right triangle. Also an isosceles triangle.
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
