the sum of the measures of the interior angles of any triangle equals 180*. the two base angles in an isoceles triangle are equal to each other so if you have the measure of one of the two base angles, then you know the other. so for example, if one base angle equals 36, then the equation to find the missing angles would be
36+36+x=180 when solved x=108, which would be the non base angle
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
The third angle must be 90 degrees, so you have an "isosceles right triangle".
Yes and the third angle would be 100 degrees
There are two equal acute angles. The third angle can be acute, right or obtuse.
Assuming you mean the third angle of a triangle... 64 degrees.
The third angle of an isosceles triangle doesn't have a name.
80
The third angle is 30 degrees and it is an isosceles triangle.
63
The triangle is an isosceles triangle.
It is an isosceles triangle because the third angle must measure 50 degrees
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle.

The sum of the interior angles of a triangle is 180o. In an isosceles triangle two of the angles are the same, say x. The third angle is then 180o-2x.
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
The total internal angles of a triangle always equal 180 degrees. Therefore, the third angle of this triangle must be 180 - 54 - 63 = 63. Since this value is the same as one of the stated sides, the triangle is indeed isosceles.
The third angle must be 90 degrees, so you have an "isosceles right triangle".
It is an isosceles triangle -- of necessity there are two identical and mirrored angles.If the third side is also equal, it is an equilateral triangle.If there is also a right angle, the other two angles are 45 degrees and it is an isosceles right triangle.
