equiangular triangle
It is impossible to have a triangle with two right angles. This is because a triangle=180 degrees. Two right angles would make up all of the 180 degrees.
A triangle that has an angle greater than 90o is an obtuse triangle.
An obtuse triangle.
First of all it is 'obtuse' because one of the angles is greater than 90 degrees. Secondly it is a ' scalene' because all the angles are of different size, this will make all the sides of different size. So the the triangle is an 'Obtuse Scalene Triangle'.

A triangle that has an angle greater than 90o is an obtuse triangle.
An obtuse triangle.
The third angle is 180-(60+70) = (180 - 130) = 50degrees.-- All of its angles aren't equal, so it's not an equilateral triangle.-- No two of its angles are equal, so it's not an isosceles triangle.-- No angle in it is 90 degrees, so it's not a right triangle.-- No angle in it is greater than 90 degrees, so it's not an obtuse triangle.--> It's an acute, scalene triangle.
The sum of interior angles in a triangle MUST add up to 180 degrees, or it is not a triangle. This works for ALL TRIANGLES! Also there must be exactly 3 angles, or it is not a triangle, hence the name Triangle. Tri (3) Angles180 degrees.
Angles fall into 4 categories and they are:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees

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). :)
It can be an obtuse triangle which includes 2 acute angles and the 3 angles add up to 180 degrees
A triangle that has 3 different acute angles that add up to 180 degrees is a scalene triangle.
Any 'random' triangle is usually 'named' after the names of its angles - so that a triangle with angles A, B and C is generally referred to as "triangle ABC" - when this format is follwoed, then the sides will generally be named in lower-case letters which correspond to the angle they oppose - so that side 'a' is opposite angle A, and so on. The only other "names" for triangles are for the type of triangle in question, if all tghe sides are the same length then it is an "equilateral" triangle, if one of the sides is a right angle (measures 90 degrees) it is a "right" triangle (or a "right-angled" triangle). If one of the angles is greater than 90 degrees it is an "obtuse" triangle, and if all the angles are less than 90 degrees it is an "acute" triangle
