That is called a "Right Triangle"
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle providing that the 3rd angle is 30 degrees.
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.
Isosceles right angled triangle, as the remaining angle must be 90o.
right triangle
Any triangle that has an angle measuring 90 degrees is a right triangle.
It is a right angle triangle and its 3rd angle is 70 degrees.
Obtuse triangle
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
It is a right angle triangle and the 3rd angle will measure 30 degrees
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.
acute-angled triangle
It is a right angle triangle providing that the 3rd angle is 30 degrees.
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.
A right angle triangle and the third angle measures 60 degrees
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
