Length of sides is irrelevant. Angles are ((180 - 40)/2) ie 70o

A triangle with two congruent sides and an angle of 104 degrees is?
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
Can a right angled triangle sometimes be a equilateral triangle?
No, since an equilateral triangle has three congruent angles of 60 degrees, and a right triangle must have an angle of 90 degrees. However, a right triangle may be an 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.
One angle of an isosceles triangle measure 100 degree what are the measures of the other two angles?
40 degrees each
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
If An isosceles right triangle is a triangle with an angle measuring ninety degrees and no two sides congruent?
No. An isosceles right triangle has the measures of 90, 45, and 45. Isosceles means that two sides are congruent. Hope this helps :)
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).
A triangle with two congruent sides and an angle of 104 degrees is?
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
What is a triangle having an angle measuring 110 degree and two congruent sides?
It is an isosceles triangle and its other two angles each measures 35 degrees
What type of triangle has two congruent sides and two measures that make 45 degrees?
Isosceles right angled triangle, as the remaining angle must be 90o.
What triangle has at least two congruent sides?
Isosceles Triangle Isosceles TriangleIsosceles triangles have at least 2 congruent sides, and equilateral triangles have all 3 sides equal. A scalene triangle has no congruent sides or angles. All triangles have 180 degrees total.An equilateral triangle has three congruent sides and an isosceles triangle has two congruent sides.
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees for kids?
It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.
An isosceles triangle that is not an equilateral triangle?
It is possible if neither of the angles in the triangle measures to 60 degrees
What is the measure of a base angle of an isosceles triangle if the vertex angle measures 38 and each of the two congruent sides measures 21 units?
Each of the base angles measure 71 degrees
If one angle of an isosceles triangle measures 60 degrees then the triangle is equilateral?
yes
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.
One angle of an isosceles triangle measures 56 degrees what are the measures of the other two angle?
62 degrees
