Only if it has a right angle and 2 acute angles
only one. the sum of angles of a triangle must equal 180 degrees. if it had two, 90+90=180. two of the lines would never meet.
then the triangle is not a right trangle and has angles that are not 90 degrees.
A triangle that has all equal sides and angles.
The 3 interior angles of a triangle add up to 180 degrees
Yes, a triangle can have 2 congruent angles.
Only if it has a right angle and 2 acute angles
only one. the sum of angles of a triangle must equal 180 degrees. if it had two, 90+90=180. two of the lines would never meet.
Isosceles triangle.
then the triangle is not a right trangle and has angles that are not 90 degrees.
A scalene triangle.
A triangle that has all equal sides and angles.
180o
The 3 interior angles of a triangle add up to 180 degrees
Right Triangle
All three angles have different values. The sum of the three interior angles is 180 degrees.
A right triangle has one angle that is always 90degrees. The other angles vary from less than 90degrees to greater than 0degrees. The equilateral triangle always has all of its angles equal to 60degrees.
