A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
An Obtuse Triangle
a 90 degree triangle
a right triangle it's called this because it has a right angle.
A 90o angle is also called a Right Angle, so a triangle that has one 90o angle is a Right angle triangle.
That's the triangle's "hypotenuse".
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 right triangle
The supplementary angle of the triangle.
A right(-angled) triangle
The longest side of a right angle triangle is the hypotenuse and it is opposite the 90 degree angle.
If each of the 3 interior angles measure 60 degrees then it is an equilateral triangle.
a right angle triangle is its name
how you name a triangle by its angles is like acute, obtuse, or right triangle. you do that by seeing if the angle has a 90 degree angle in it then its a right angle, if all the angles are 90 degrees or less than its an acute triangle. and if the triangle has one angle that is over 90 degrees than it is an obtuse triangle. to name a triangle by its sides is if its equilateral, equiangular, or regular. if its equilateral then all the sides are congruent. if its equiangular then all the angles are congruent. if its regular, then all the sides and angles are congruent to each other (for example and octogon). :)

An angle greater than 90 degree is an obtuse angle.
The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.
The third angle of an isosceles triangle doesn't have a name.
The name of the point at which all of a triangle's angle bisectors converge is the incenter.
It is called a right triangle.
