No, one angle of a right triangle cannot be 100 degrees because the sum of the interior angles of a triangle is always 180 degrees. In a right triangle, one angle is always 90 degrees, leaving the other two angles to add up to 90 degrees as well. Therefore, if one angle is 100 degrees, the other two angles would have to add up to 80 degrees, which is not possible in a right triangle.

Vivino, the definition of a right triangle is that one of its angles is 90 degrees while the other 2 are 45 degrees wrong... the other angles can be any angle less than 90 so long as one angle is exactly 90 degrees it is still a right triangle. ps. it is more appropriate when improving answer to add your comment not delete someone elses... your absolutely right. that was my bad. that was actually an awful answer on my part. didn't mean to delete yours.

If one angle of a triangle is 100 degrees what type of triangle is it?
Obtuse triangle
What type of triangle has an angle that measures 100 degrees and an angle that measures 50 degrees?
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
What is the measure of the third angle of the triangle if the measures of two angles of a triangle are 35deg and 45deg?
The missing angle measure is 100 degrees.
The supplement of a 80 degree angle has a measure of?
The supplement of an 80 degree angle is an 100 degree angle.
What type of triangle can an isosceles triangle be scalene right acute obtuse?
What are the properties of the various triangles given:Isosceles triangles have two sides equal, two angles equalScalene triangles have all three sides different and all three angles differentRight triangles have one angle which is a right angle (90°)acute triangles have all angles less than 90°obtuse triangles have one angle greater than 90°As an isosceles triangle has two sides equal, it cannot be a scale triangle which has all three angles different.For the other three properties, consider:The sum of the angles in a triangle is 180°If one angle is 90°, the other two angles could be: (180° - 90°) / 2 = 45° each - two angles the same→ an isosceles triangle could be a right triangleIf all angles are less than 90°, let one angle be 80°, the other two angles could be: (180° - 80°) / 2 = 50° each - two angles the same→ an isosceles triangle could be an acute triangle(Note that if one angle was 60°, then the other two being equal would be: (180° - 60°) / 2 = 60° each making all three angles the same and the triangle an equilateral triangle)If one angle is greater than 90°, let it be 100°, the other two angles could be: (180° - 100°) / 2 = 40° each - two angles the same→ an isosceles triangle could be an obtuse triangleFrom the given list, an isosceles triangle could be a right, acute or obtuse triangle, but it could not be a scalene triangle.
