A triangles angles have to add up to 180 degrees so since there are two angles that measure 40 it is 180-80=100(answer.)
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 base angles will have equal angles of 50 degrees
The two equal angles each measure 45 degrees
In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
The three interior angles measure 45, 45 and 90 degrees.
That's an isosceles triangle.
A right triangle. Also an isosceles triangle.
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
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
In an isosceles triangle, two angles are equal. Since the angles provided are 54 degrees and 63 degrees, the equal angles must be 54 degrees. The sum of the angles in any triangle is 180 degrees. Thus, the measure of the third angle is calculated as follows: 180 - 54 - 54 = 72 degrees.
The 3 interior angles are 90 degrees, 45 degrees and 45 degrees
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
It is a right angle triangle and it can also be considered as an isosceles triangle
