There are no triangles with only one angle.
Equilateral triangles have only acute angles ti be equal to each other
No. All triangles MUST have at least two acute angles.
Triangles can only have an internal angle sum of 180, if you have two angles at 90 degrees, their sum would be 180 leaving no more degrees to create the last angle.
Infinitely many. Having found one triangle, you can find infinitely many similar triangles.
There are no triangles with only one angle.
Only in right angle triangles
Equilateral triangles have only acute angles ti be equal to each other
No. All triangles MUST have at least two acute angles.
No. Right triangles are triangles with one angle exactly 90°, and obtuse angles are triangles with exactly one angle that is greater than, but not equal to, 90°.
Not possible. There are an infinite number of triangles that all have that same one angle in them.
Triangles can only have an internal angle sum of 180, if you have two angles at 90 degrees, their sum would be 180 leaving no more degrees to create the last angle.
All right-angles triangles. That is triangles that contain one angle at 90 degrees.
Of all the triangular shapes, only a right angle triangle has one right angle (90 degrees).
Infinitely many. Having found one triangle, you can find infinitely many similar triangles.
The right angle is the largest. Triangles have a total of 180 degrees. If you use 90 on one angle, you only have 90 for the other two.
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
