An triangle with 2 equal angles.
Sum of all angles in a triangle is equal to 180o. If two angles are 60o then the third angle is: Third angle = 180o - (60o + 60o) = 60o. But a right triangle is one having one angle equal to 90o but in this case there is no angle equal to 90o. So there is no right triangle which has two angles equal to 60o.
No. It need not be the base angles that are equal, it can be one of the base angles and the top angle (if the triangle is tipped over). Also, the base angle are equal in an equilateral triangle - although an equilateral triangle is a special kind of isosceles triangle.
If it is an equilateral triangle then it will have 3 equal angles If it is an isosceles triangle then it will have 2 equal angles plus another different size angle
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.
That isn't possible. A triangle always has 3 sides. But, a triangle can have no equal sides. That's possible. But a triangle angle with no sides or angles? Nope.
A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.
The opposite exterior angle.
The angles of the sides are equal to the angle of the top.
acute angle is an angle that is less that 90 degrees. An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.
All triangles have 3 interior angles that add up to 180 degrees and they are:- Right angle triangle: 90 degree angle and 2 acute angles Obtuse triangle: An obtuse angle and 2 acute angles Scalene triangle: 3 acute angles of different sizes Isosceles triangle: 2 equal angles and another angle Equilateral triangle: 3 equal angles that each measures 60 degrees
