Yes, the definition of a right triangle is that it has a 90 degree angle
acute * * * * * No. It is a right angled triangle.
A right(-angled) triangle
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
A right angle triangle has a 90 degree angle and 2 acute angles
Because the Bottom left corner makes a 90 degree angle like this |_ and a 90 degree angle is called a Right angle thus the name Right angled Triangle
A triangle with a 90 degree angle and two 45 degree angles.
A right-angled triangle.
Yes, when it has a 90 degree and two 45 degree angles it is an isosceles right angled triangle.
The right-angled triangle.
A right angle triangle
If you mean right angled triangle then the answer is "no" a right angled triangle must have one angle 90 degree if you dont then answer is "yes" cause the sum of angles is equal to 180 degree
