No because the 3 angles of a triangle must add up to 180 degrees no less and no more
'a' and 'b' must both be acute, complementary angles.
Any triangle with a 90 degree angle is classified as a right triangle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
Obtuse triangle
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.
acute-angled triangle
It is a right angle triangle and the 3rd angle will measure 30 degrees
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
It is a right angle triangle providing that the 3rd angle is 30 degrees.
