Since All the Angles of a Triangle add up to 180o and Since we know that Two Sides (and therefore two Angles) in an Isosceles are equal.
So we can get the SUM of the other two angles is 180o - 50o = 130o.
And therefore the other two angles are 130o / 2 = 65o

Why does the acute angles in an isosceles right triangle always measures 45 degrees?
The question lists three facts: "triangle", "right", and "isosceles". Each fact carries important information. -- "triangle" ... The three angles in any triangle always add up to 180 degrees -- "right" ... One angle in a right triangle must be a right angle = 90 degrees. That leaves the other 90 degrees for the other two angles to share. -- "isosceles" ... Two of the angles in an isosceles triangle are equal. If there are 90 degrees to share between them, then each of them is 45 degrees.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.
One angle of an isosceles triangle measure 100 degree what are the measures of the other two angles?
40 degrees each
What are the angles of a right isosceles triangle?
The two other angles are 45 degrees each. The three angles of every triangle always add up to 180 degrees. -- A right triangle is a triangle that has a right angle in it. -- A right angle is 90 degrees. -- That leaves 90 degrees for the other two angles in the right triangle. -- If it happens to be isosceles, then the other two angles are equal. -- Those must both be 45 degrees.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42?
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
What are the measures of the base angles of a right isosceles triangle?
45 degrees.
An isosceles triangle that is not an equilateral triangle?
It is possible if neither of the angles in the triangle measures to 60 degrees
How do you find the measures of the angles in a right isosceles triangle?
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
What is a triangle that has angles that measures 45 45 90 degrees?
It is an isosceles triangle. 45 + 45 + 90 = 180 degrees
What are the measures of all the angles in an isosceles right triangle?
They are: 45, 45 and 90 degrees
What is the measure of the base angle of an isosceles triangle if the vertex measures 38 degrees?
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
If the measures of two angles of an isosceles triangle are 54 degrees and 63 degrees what is the measure of the third angle?
63 degrees
One angle of an isosceles triangle measures 100 degreas What are the measures of the other 2 angles?
The other two angles will be 40 degrees each.
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees?
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
What are the measures of all the angles n an isosceles right triangle?
180 Two angles are 45 degrees and between them the third angle is 90 degrees.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 48?
84 degrees
What is the measure of the vertex angle of an isosceles triangle if one of the base angles measures 48?
84 degrees
