Obtuse triangle
It is a right angle triangle and its 3rd angle is 70 degrees.
acute
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.
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
Obtuse triangle
It is a right angle triangle and its 3rd angle is 70 degrees.
Any triangle that has an angle measuring 90 degrees is a right triangle.
acute-angled triangle
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.
right triangle and the other angle would be 70 degrees. Hope I helped :)
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
The 3rd angle is 30 degrees which would form an obtuse or scalene triangle.
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
