Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
If it has a 90 degree angle and two acute angles then it is a right angle triangle.
A triangle with a 90 degree angle and two acute angles is a right angle triangle.
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
It is an isosceles right angle triangle.
== == The corresponding angle is 60 degrees.
It is an isosceles triangle.
It is a right angle triangle
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
If it has a 90 degree angle and two acute angles then it is a right angle triangle.
A triangle with a 90 degree angle and two acute angles is a right angle triangle.
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
It is an isosceles right angle triangle.
A right angle triangle has a 90 degree angle and two interior acute angles
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.
They have one 90 degree angle and two 45 degree angles
