An isosceles triangle
Angles have toad to 180 degrees to be triangle so you have no triangle as angles add to 190. If angle is 116 degrees instead of 126 degrees you have isosceles triangle
Any triangle that has an angle measuring 90 degrees is a right triangle.
Scalene
acute-angled triangle
That depends on what type of shape it is as for example a triangle can only have 1 right angle of 90 degrees.
In an equilateral triangle all the angles are 60 degrees (i.e. acute angles)
The total when you add up the three angles in a triangle is 180 degrees.If one angle is 100 degrees, then the total of the other two angles is 80 degrees. This means that those two angles must SMALLER than 90 degrees.So a triangle with an angle of 100 degrees cannot be a right triangle.
There is no such triangle because the 3 interior angles of any triangle add up to 180 degrees.
That depends on the type of triangle it is but in general the 3 interior angles of any triangle add up to 180 degrees.
180 degrees. sum of every angle of triangle is always 180..no matter what type of triangle it is.
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
A right angles triangle, as one of the angles in the triangle is 90 degrees.
Depends on the type of triangle. A right-angled triangle has ONE right angle - the remaining two angles total 90 degrees.
That depends on what type of triangle it is but the 3 interior angles of any triangle add up to 180 degrees
Only right triangles have right angles. An equilateral triangle though can't have a right angle because all the angles in any type of triangle must add up to 180 degrees. For each angle to be equilateral, they must be 60 degrees, showing that there is no angle at 90 degrees in an equilateral triangle, which would signify that it would be right.
All angles of an equilateral triangle are congruent, in other words, they all have the same angle measure. Since these three equal angles must add up to 180 degrees, each angle must have the measure of 60 degrees. This is because 60 X 3 = 180 degrees. So, the angles of an equilateral triangle are all equal to 60 degrees. An angle that is less than 90 degrees is an acute angle, and since 60 is less that 90, the angles of an equilateral triangle are acute.
