A triangle that has all equal sides and angles.
All three angles have different values. The sum of the three interior angles is 180 degrees.
Only if it has a right angle and 2 acute angles
No. The sum of all three angles must is 180 degrees. If there are 2 right angles (ie two angles of 90 degrees each), there is no scope for the third angle.
obtuse angles are larger than 180 degrees. acute are smaller than 180. for example ina trangle, the exterior angles are obtuse and the inner angles are acute.
Yes, a triangle can have 2 congruent angles.
A scalene triangle.
A triangle that has all equal sides and angles.
180o
All three angles have different values. The sum of the three interior angles is 180 degrees.
Only if it has a right angle and 2 acute angles
Isosceles triangle.
No. The sum of all three angles must is 180 degrees. If there are 2 right angles (ie two angles of 90 degrees each), there is no scope for the third angle.
obtuse angles are larger than 180 degrees. acute are smaller than 180. for example ina trangle, the exterior angles are obtuse and the inner angles are acute.
the fire trangle is the trangle that is on fire
180
then the triangle is not a right trangle and has angles that are not 90 degrees.
