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.
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.
Does a right angle triangle have 90?
A right triangle is a triangle in which one of the three angles measures 90°. In other words, it is a triangle with two sides that are perpendicular to each other.
Can an obtuse triangle have congruent angles?
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
How to Prove that a triangle cannot have two right angles?
The sum of the interior angles of a triangle is 180 degrees. If one angle is 90, that leaves 90 for the other two angles. You can't have another angle of 90 and an angle of 0, so there can only be one angle in a triangle that measures 90 degrees.

How do you know what angles in a triangle are worth using algebra?
If the triangle is equilangular, then all angles are 60 degrees: 180/3 = 60 If the measures of two angles are given, you can discover the 3rd one by subtracting the sum of the two angles from 180.
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.
In a right triangle if one angle is 35 what are the measures of the other two angles?
90 (of course) and 55

If the sum of the measures of two angles of a triangle is equal to the measure of the third angle the triangle must be?
...a right triangle.

If the measures of two angles of an isosceles triangle are what is the measure of the third angle?
63
What triangle has one angle that measures 40 degrees one angle that measures 90 degrees and another angle that measures 50 degrees?
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
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.
