A Right- Angled triangle.
Also
Equilatertal ; the three sides are of equal length, and the three angles are all 60 degrees.
Isosceles ; two sides of equal lnegth, and two angles of equal size.
Scalene ; all three sides are unequal in length, and all three angles are different.
In all cases the sum on the three interior angles equals 180 degrees.

How many diagonals does a right angle triangle have?
The only diagonal line in a right-angle triangle is the hypotenuse. So the answer is 1.
How many acute angles does a right triangle have?
A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.
If the side opposite angle A of a right triangle is 30 meters and the hypotenuse is 90 meters what is the sin of angle a?
sin of angle a = opposite/hypotenuse = 1/3 sin-1(1/3) = 19.47122063 degrees
What is a 3-sided polygon with 1 right angle and no equal sides?
2
What is the minimum number of right angles there can be?
That depends on what type of shape it is as for example a triangle can only have 1 right angle of 90 degrees.
