What shape has 4 sides and all angles equal?
Presuming our geometry is Euclidean, such a shape would be a rectangle, since all 4 angles would be right angles. If our geometry is hyperbolic, it would be possible to construct such a quadrilateral which is not a rectangle (and in fact, rectangles cannot exist in a hyperbolic geometry). I do not believe such a quadrilateral has any special name.
Can a right triangle can be an equilateral triangle?
Short Answer: no Long Answer: Most people consider Euclidean Geometry when taking about standard shapes such as triangles and squares. In Euclidean Geometry: all equilateral triangles have angles of 60°. Therefore an equilateral triangle doesn't have a right angle. However, in Non-Euclidean Geometry (Elliptic Geometry) a triangle can have all angles at 90°. Consider going for a walk at the North Pole. Start going South (all directions are South), then turn at a right angle (90°) to go East, then turn again at a right angle (90°) to go North and you would end up at your starting point (assuming the distance travelled in each direction is the same). The 'triangle' you made would have 3 right angles!!
What is a triangle with angles that are 60 degrees?
That would be an equilateral triangle.
Are two equiareal right-angled triangles always congruent?
An equilateral right-angled triangle is an impossibility in plane geometry as it would need to have internal angles totalling 270 degrees.
What is a triangle with angles of 60 degrees and 30 degrees?
The third angle has to be 90 degrees so it would be a right angle triangle.

A triangle has one angle of 80 degrees and another of 60 degrees how many degrees must there be in the third angle?
40 degreesMathematically there are 180 degrees in a triangle. So 180 -60 -80 = 40 degrees which is your answer

What triangle has the measures 41 degrees and 74 degrees?
That would be an acute scalene triangle.
What triangle has 39 degrees 64 degrees and 77 degrees?
A scalene triangle would fit the given conditions

That would be an equilateral triangle.

What type of triangle would have degrees of 45 96 and 39?
It would be an obtuse triangle.
What is a triangle with angles of 60 degrees and 30 degrees?
The third angle has to be 90 degrees so it would be a right angle triangle.
Is there a right triangle in an equiangular triangle?
No there is not. A right triangle has to have an angle of 90 degrees. An equiangular triangle has 3 equal angles. If a right triangle was equiangular, it would be 90 times 3 equaling 270 degrees. There are only 180 degrees in a triangle.
Which kind of triangle is 115 and 30 degrees?
It is an obtuse triangle and the third angle would measure 35 degrees
Is an isosceles triangle similar to a right triangle?
It can be similar to each other with the base angles theorem. It would be 90 degrees and on the bottom would be both 45 degrees and if you would turn it sideways, there is your right triangle.
