What are the sizes of the the other angles in an isosceles triangle when one of them is 98 degrees?

It is 180-98 = 82 and 82/2 = 41
So the 3 angles are: 98 degrees, 41 degrees and 41 degrees because 2 angles in an isosceles triangle are equal in size.

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 maximum vertex angle in an isosceles triangle?
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
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 is the vertex angle of isosceles right triangle?
An isosceles triangle has two equal sides, and if one of the angles is 90 degrees, than the other two have to be equal. A triangle's angles always add up to 180 degrees, so the other two have to be 45 degrees.
If an isosceles triangle has a angle of 30 degrees find the size of the other angles in the triangle?
There are 180 degrees in a triangle, so 180 minus 30 is 150. Since it's an isosceles triangle, that means the other two angles angles are the same, so 150 divided by 2 is 75.
If the base angle is of an isosceles triangle is 35 degrees what is the measurement of the other two angles?
35 and 110 degrees (180 degrees in a triangle)
What are the angle measurements for an isosceles right triangle?
An isosceles triangle has two sides and angles that are equal, causing it to have exactly a line of symmetry through it. A right triangle has one angle that is 90 degrees. An isosceles right triangle will always have one angle that is 90 degrees, while the other two angles will be 45 degrees.
What angels are there in an isosceles?
In a isosceles triangle, all angles are less than 90 degrees and therefore they are acute angles. Two angles on the opposite side of each other are equal angles.
What is the triangle that is an angle of 120 degrees?
If the other two angles are equal then it's an isosceles triangle if they are not equal then it's an obtuse triangle.
Is it possible to draw a right isosceles triangle?
Yes. The other two angles will be 45 degrees.
Is is possible to have an isosceles right triangle?
Yes, but the other two angles must be 45 degrees.
Is a right triangle can be isosceles?
Yes. Only if the other two angles of the right triangle are congruent and each equal 45 degrees. Then using the isosceles triangle theorem, you know that the two sides opposite the angles are congruent.
